preserve null value in buffer resize
add delta to readme

update tracks
fix logscale error
add condition to not consider zero transition edges for any dynamic programming logic.  should be big speedup with now change in result.  also made cython use same zerolog val as python
Merge branch 'byekit' into same
undo lneta optimzations since there are problems in mstep now
add shift track attribute to add constant factor before scaling
remove reduced tracks because do not want to maintain
undo change from last byekit merge where zero transitions skipped, because it didnt work
Merge branch 'same' of github.com:glennhickey/teHmm into same
new dp omptimization to avoid computing exponents of zero edges
fix typo in path
regen clean tracks
strip deltas from default tracks xml, leave that in the same branch
add new ltr element to truth
