added hybridslater2, which should handle heavy atoms beyond C
fitme.parHF is now being updated, so that epsDensity2 will be used to avoid re-initialization of density matrices
model3.E2 now does full trace over density matrix
model3.E2fast is the older method that works only if HF was solved for these paramters
model3.modelCalcParallel uses E2fast if density was recomputed, and E2 otherwise

Fast evaluation of jacobian of the err:
   Model3 now caches operators H1 H2 KE
   Model3 cache evaluation takes advantage of situations where only 1 mixer changes
   Fitme.errJac is new function that uses Model3 for Jacobian evaluation
   Fitme.err implementation of parallel algorithm fundamentally changed
         change in parallel approach was due to file read/write becoming rate limiting
   parallelHF is new global function called by Fitme.err
obj.parallel set to matlabpool('size') and saveForParallel is 20 times this.
