Optimized fitApplyMPO methods to use only one vector for storing blocks. Minor cleanup of imagTEvol.
Minor cleanup of imagTEvol.
Changed name of debug mode objects folder under matrix folder to .debug_objs
Removed combine_mpo option from LocalOp for simplicity.
Updated zipUpApplyMPO to use OptSet instead of cutoff and maxm arguments.
Improved multiplication pattern for applyExpH and implementing 'flipping' optimization. Changed order of arguments to fitApplyMPO to match zipUpApplyMPO. Made an optimization where partial wf and projected H tensors are reused to grow left and right tensors.
Switched imagTEvol to use applyExpH.
Fixed propagation of opts through orthMPS.
Added comment on how to use timers feature in prodstats.h
