Minor fixes and tracking aids:

(a) UserInquiries_standalone.py
     - Print edge labels alphabetically
     - Moved "break" so that inquiry about a deleted edge no longer prints info instead about final edge in list
     - Temporary code to check for possible index duplication (commented out, but accessible if desired in future)
(b) lxa5.py
     - Similar changes as in (a) for the UserInquiries section of this file
     - Record # of Edges and # of States prior to merge loop in order to check for possible index duplication during merges
(c) fsa.py
     - Use set union instead of list extend when merging lists of edge labels
     - Additional printfs during merge process
     - Explanatory comments about possibility of index duplication in the two 'mergeTwoStatesCommon...' functions

Brings repository up-to-date for clear demarcation from next step (re merges)
