Some ToDo's

• [X] Add implementation for polydisperse packings. :heavycheckmark:
• [X] Add support for Mosek solver. :heavycheckmark:
• [ ] Add implementation with closed boundary conditions
• [ ] Try to implement model creation with direct_model instead of Model (to avoid copying the model).
  • Currently, when direct model is used it throws the error The solver does not support an objective function of type MathOptInterface.SingleVariable. when using HiGHS (and possibly with other solvers similar errors occur).
• [ ] Finish the Issues section of the documentation
• [ ] Try adding examples using Literate.jl
• [ ] Add functions to analyse packings (e.g. compute gaps, extract forces –distinguishing bucklers–, etc.)
