#2931:

  • created LinearProgrammingAlgorithm
    • created definitions for all LP/MIP solvers supported by OR-Tools
  • created LinearProgrammingProblem
    • created classes required for scripting: LinearProgrammingProblemDefinition, LinearProgrammingProblemDefinitionScript, CompiledLinearProgrammingProblemDefinition
    • created views: LinearProgrammingProblemView, LinearProgrammingProblemDefinitionScriptView
  • updated OR-Tools version in ExtLibs to 6.9
