Put a place holder into the skelton's histogram directory to ensure
that it is part of the repo
Added a filter height variable to the LendaChannel Class.
It will store the max Fast Filter value.  Added the clear statement
to .cc file
Added more detailed comment box in the LendaPacker header.  Added a
thisEventsFilterHeight variable.  Did some clean up/added comments in
LendaPacker.cc.  In Calc Energy checks to see if the FF has been
calculated, if not it calculates it and the CFD fitler.
It is needed to calcualte the max filter height.
Added a getMaxPulseHeight method that takes a vector of Doubl_t's
so that the packer can send the fast filter.  Should at one point
got through and make the fast filter Int_t's.  Should also template
some of the methods in the filter class
