v0.1.1

Added

• Use the catkin tag inside C++ configuration to make rtcg-gen produce
  Catkin package.xml and CMakeLists.txt files for each test. This is
  experimental. Inside the catkin tag, the package sub-tag contains a
  simplified implementation of the Catkin v2 package format.

Changed

• STM suites now contain unified inferred channel types as well as the
  generated tests. This means there is now an extra level of nesting in the
  data structure: tests are under tests, types are under types (and are
  a map from channel names to type info). See examples/bmon/stms.json.
• There is now only one convert.h generated, and it uses the unified types
  stored in the STM.
• Both convert.cpp and the newly unified convert.h now appear in the
  convert subdirectory of the source root (alongside rtcg etc).
• Input directory structures now more closely match output directory
  structures. For example, convert.cpp must now be in
  $INPUT/$VARIANT/src/convert/convert.cpp, which matches where it will be
  generated in the output.
• (Accidentally omitted from changelog as released): Initial delay and timeout
  callbacks now only fire when waiting to start or running respectively, which
  should fix a bug with these timeouts firing repeatedly.
