cplex-scala-1.5.0

• Update Gradle wrapper to release 5.4
• Add API for multi-objective in MpModel: see example DietMultiObj.scala
• Define method apply in classes NumArray, IntArray and IntExprArray for element constraint: this allows to write constructs like cost = costs(supplier) where costs is an array of integer, supplier is an integer variable and cost is an integer expression that represents the cost of the supplier. See Facility.scala for a complete example.
• Add operator * on classes NumArray, IntArray, NumVarArray and IntExprArrayfor scalar product.
• Refactoring:
  • Add class Modeler to build optimization model: CpModel and MpModel now inherits from Modeler
  • Move many classes such as NumExpr, IntExpr, NumVar, IntVar, Objective from package com.decisoinbrain.cplex.mp and com.decisionbrain.cplex.cp to com.decisionbrain.cplex.
  • These entities are now shared and can be used to build either a mathematical programming model or a constraint
    programming model.
• Update file build.gradle: replace dependency with oplall.jar by dependencies with cplex.jar and
  ILOG.CP.jar instead.
