sasoptpy v0.1.2

New Features
++++++++++++

• As an experimental feature, sasoptpy supports saspy connections now
• Model.solve_local method is added for solving optimization
  problems using SAS 9.4 installations
• Model.drop_variable, Model.drop_variables,
  Model.drop_constraint, Model.drop_constraints methods are
  added
• Model.get_constraint and Model.get_constraints methods are
  added to grab Constraint objects in a model
• Model.get_variables method is added
• _dual attribute is added to the Expression objects
• Variable.get_dual and Constraint.get_dual methods are added
• Expression.set_name method is added

Changes
+++++++

• Session argument accepts saspy.SASsession objects
• VariableGroup.mult method now supports pandas.DataFrame
• Type check for the Model.set_session is removed to support new session
  types
• Problem and solution summaries are not being printed by default anymore,
  see Model.get_problem_summary and Model.get_solution_summary
• The default behavior of dropping the table after each solve is changed, but
  can be controlled with the drop argument of the Model.solve method

Bug Fixes
+++++++++

• Fixed: Variables do not appear in MPS files if they are not used in the model
• Fixed: Model.solve primalin argument does not pass into options

Notes
+++++

• A .gitignore file is added to the repository.
• A new example is added: Decentralization.
• Both CAS/Viya and SAS versions of the new example are available.
• There is a known issue with the nondeterministic behavior when creating MPS
  tables. This will be fixed with a hotfix after the release.
• A new option (no-ex) is added to makedocs script for skipping examples when
