abstract: An embedded proximal interior point quadratic programming solver, which
  can solve dense and sparse quadratic programs, described in Schwan, Jiang, Kuhn,
  and Jones (2023) <https://doi.org/10.48550/arXiv.2304.00290>. Combining an infeasible
  interior point method with the proximal method of multipliers, the algorithm can
  handle ill-conditioned convex quadratic programming problems without the need for
  linear independence of the constraints. The solver is written in header only 'C++
  14' leveraging the 'Eigen' library for vectorized linear algebra. For small dense
  problems, vectorized instructions and cache locality can be exploited more efficiently.
  Allocation free problem updates and re-solves are also provided.
