Setting the basis for spelling/trans split
Basic division of spelling and trans works

Need to test digraphs in loading
Need to implement digraph creation (N-graph?)
Need to change running text to return non-frequency dictionary corpus
Lots of progress and most everything works

Digraphs don't work quite yet
quick fix
Fixed a couple of issues

Find word tokens works
Case insensitive (sort of) look up works
Small fix maybe?
Digraphs should be working
Merge in from master
Analysis windows should be working again

All of them use sequence_type instead of string_type
File IO for neighdens works (loading list of words to calc and
outputting a list of neighbors found)
