+Access control list (acl) module. An acl is a list of account addresses who
+have the access permission to a certain object.
+This module uses a vector to represent the list, but can be refactored to
+use a "set" instead when it's available in the language in the future.

+## Function `cmp_bcs_bytes`
+
+Compare v1 and v2 using
+(1) byte-by-byte comparison from right to left until we reach the end of the shorter vector,
+then
+(2) vector length to break ties.
+Returns either EQUAL (0u8), LESS_THAN (1u8), or GREATER_THAN (2u8).
+This function is designed to compare BCS (Starcoin Canonical Serialization)-encoded values
+(i.e., vectors produced by BCS::to_bytes). A typical client will call
+Compare::cmp_bcs_bytes(BCS::to_bytes(&t1), BCS::to_bytes(&t2)). The comparison provides the
+following guarantees w.r.t the original values t1 and t2:
+- cmp_bcs_bytes(bcs_ext(t1), bcs_ext(t2)) == LESS_THAN iff cmp_bcs_bytes(t2, t1) == GREATER_THAN
+- Compare::cmp<T>(t1, t2) == EQUAL iff t1 == t2 and (similarly)
+Compare::cmp<T>(t1, t2) != EQUAL iff t1 != t2, where == and != denote the Move
+bytecode operations for polymorphic equality.
+- for all primitive types T with < and > comparison operators exposed in Move bytecode
+(u8, u64, u128), we have
+compare_bcs_bytes(bcs_ext(t1), bcs_ext(t2)) == LESS_THAN iff t1 < t2 and (similarly)
+compare_bcs_bytes(bcs_ext(t1), bcs_ext(t2)) == LESS_THAN iff t1 > t2.
+For all other types, the order is whatever the BCS encoding of the type and the comparison
+strategy above gives you. One case where the order might be surprising is the address type.
+CoreAddresses are 16 byte hex values that BCS encodes with the identity function. The right to
+left, byte-by-byte comparison means that (for example)
+compare_bcs_bytes(bcs_ext(0x01), bcs_ext(0x10)) == LESS_THAN (as you'd expect), but
+compare_bcs_bytes(bcs_ext(0x100), bcs_ext(0x001)) == LESS_THAN (as you probably wouldn't expect).
+Keep this in mind when using this function to compare addresses.

+# Module `0x1::Errors`
+
+Module defining error codes used in Move aborts throughout the framework.
+
+A u64 error code is constructed from two values:
+
+1. The *error category* which is encoded in the lower 8 bits of the code. Error categories are
+declared in this module and are globally unique across the Diem framework. There is a limited
+fixed set of predefined categories, and the framework is guaranteed to use those consistently.
+
+2. The *error reason* which is encoded in the remaining 56 bits of the code. The reason is a unique
+number relative to the module which raised the error and can be used to obtain more information about
+the error at hand. It is mostly used for diagnosis purposes. Error reasons may change over time as the
+framework evolves.
+
+Rules to declare or use *error reason*:
+1. error reason is declared as const in the user module
+2. error reason name must start with "E", for example, const EACCOUNT_DOES_NOT_EXIST = ...
+3. value less than 100 is reserved for general purpose and shared by all modules
+4. don't change general purpose error reason value, it's co-related with error code in starcoin vm
+5. self-defined error reason value must be large than 100
+6. error reason must be used together with error category

+# Module `0x1::Event`
+
+The Event module defines an EventHandleGenerator that is used to create
+EventHandles with unique GUIDs. It contains a counter for the number
+of EventHandles it generates. An EventHandle is used to count the number of
+events emitted to a handle and emit events to the event store.

+
+
+Currently, we ignore the actual implementation of this function in verification

+
+Abstracting this and related functions is possible because the correctness of currency
+conversion (where FixedPoint32 is used for) is not relevant for the rest of the contract
+control flow, so we can assume some arbitrary (but fixed) behavior here.

+# Module `0x1::FromBCS`
+
+This module provides a number of functions to convert _primitive_ types from their representation in std::bcs
+to values. This is the opposite of bcs::to_bytes. Note that it is not safe to define a generic public from_bytes
+function because this can violate implicit struct invariants, therefore only primitive types are offerred. If
+a general conversion back-and-force is needed, consider the StarcoinFramework::Any type which preserves invariants.
+
+Example:
+```
+use std::bcs;
+use StarcoinFramework::from_bcs;
+
+assert!(from_bcs::to_address(bcs::to_bytes(&@0xabcdef)) == @0xabcdef, 0);
+```

+
+
+
+## Struct `GasSchedule`
+
+The gas schedule keeps two separate schedules for the gas:
+* The instruction_schedule: This holds the gas for each bytecode instruction.
+* The native_schedule: This holds the gas for used (per-byte operated over) for each native
+function.
+A couple notes:
+1. In the case that an instruction is deleted from the bytecode, that part of the cost schedule
+still needs to remain the same; once a slot in the table is taken by an instruction, that is its
+slot for the rest of time (since that instruction could already exist in a module on-chain).
+2. The initialization of the module will publish the instruction table to the genesis
+address, and will preload the vector with the gas schedule for instructions. The VM will then
+load this into memory at the startup of each block.

+# Module `0x1::Vector`
+
+A variable-sized container that can hold any type. Indexing is 0-based, and
+vectors are growable. This module has many native functions.
+Verification of modules that use this one uses model functions that are implemented
+directly in Boogie. The specification language has built-in functions operations such
+as vec. There are some helper functions defined here for specifications in other
+modules as well.
+
+>Note: We did not verify most of the
+Move functions here because many have loops, requiring loop invariants to prove, and
+the return on investment didn't seem worth it for these simple functions.

+/// A `u64` error code is constructed from two values:
+///
+///  1. The *error category* which is encoded in the lower 8 bits of the code. Error categories are
+///     declared in this module and are globally unique across the Diem framework. There is a limited
+///     fixed set of predefined categories, and the framework is guaranteed to use those consistently.
+///
+///  2. The *error reason* which is encoded in the remaining 56 bits of the code. The reason is a unique
+///     number relative to the module which raised the error and can be used to obtain more information about
+///     the error at hand. It is mostly used for diagnosis purposes. Error reasons may change over time as the
+///     framework evolves.
+///
+/// Rules to declare or use *error reason*:
+///  1. error reason is declared as const in the user module
+///  2. error reason name must start with "E", for example, const EACCOUNT_DOES_NOT_EXIST = ...
+///  3. value less than 100 is reserved for general purpose and shared by all modules
+///  4. don't change general purpose error reason value, it's co-related with error code in starcoin vm
+///  5. self-defined error reason value must be large than 100
+///  6. error reason must be used together with error category
