pH dependence of carbonic anhydrase

1) checked the equation for Keq in CCMParams.m ( plot just this with
pHvsKeq.m)
2) replaced the haldane relationship with a pH dependent relationship
and integrated into the analytic solution for when carbonic anhydrase
is  unsaturated.
3) Moved the calculation of the analytic solution for the whole CCM
model into FullCCMAnalyticSolution.m  sot that CH_conc_Csome.m is no
longer necessary.
4) deleted extra unnecessary files that were calculating analytic
solutions
return two files

These were used somewhere I wasn’t aware of.
