This is a very simple class to guide algorithms.
It is used to tidy up passing parameters to initialSolve and maybe for output from that

Special options - bits 0 4 - use crash (default allslack in dual, idiot in primal) 8 - all slack basis in primal 2 16 - switch off interrupt handling 3 32 - do not try and make plus minus one matrix 64 - do not use sprint even if problem looks good.
which translation is: which: 0 - startup in Dual (nothing if basis exists).: 0 - no basis 1 - crash 2 - use initiative about idiot! but no crash 1 - startup in Primal (nothing if basis exists): 0 - use initiative 1 - use crash 2 - use idiot and look at further info 3 - use sprint and look at further info 4 - use all slack 5 - use initiative but no idiot 6 - use initiative but no sprint 7 - use initiative but no crash 8 - do allslack or idiot 9 - do allslack or sprint 10 - slp before 11 - no nothing and primal(0) 2 - interrupt handling - 0 yes, 1 no (for threadsafe) 3 - whether to make +- 1matrix - 0 yes, 1 no 4 - for barrier 0 - dense cholesky 1 - Wssmp allowing some long columns 2 - Wssmp not allowing long columns 3 - Wssmp using KKT 4 - Using Florida ordering 8 - bit set to do scaling 16 - set to be aggressive with gamma/delta? 32 - Use KKT 5 - for presolve 1 - switch off dual stuff 6 - extra switches
