- refactored QP_solver to separate the QP, the ET and the Tags
- got rid of MPS.h, MPS.C (integrated into QP_models)
- added QP_functions.h to test full rank of QP
- added QP_solver diagnostics for friends to access
- removed ET type from MPS reader (was only needed for rank test, and now
I'm using the new QP function for that -> faster and cleaner)
- NAMEs with spaces
- RANGES
- RHS entry for objective row (means: constant term in obj func)
enhanced QP_solver. It can now handle a constant term in obj func
