updates to TDA analysis module

- define a bunch of new histograms
- Refactor init method (divide into smaller funcs called sequentially)
Move filler to its own pandaroot module

- On the way split into a header and source file
- No pandaroot dependence is introduced. If needed it will be very easy to
  compile it separately. This was done just for ease of use in panda
  analysis modules.
