-There are two sets of files to support model 1 & 2 . I kept them separate as the models are wired quite different Model 1 address by digit, while Model 2 address by segment. So the code is quite different for both for many functions. Also helps with hardware  testing modularity and testing.

 The same ASCII font file is used by both sets of files.
 Model 3 uses same code base as Model 1, just different example file and different use of setLED functions.

 also these results where pre v1.6 so buttons issue should be fixed. In theory changing the shiftout routine's the same way as shiftin changed in v1.6 should fix any display issues here.
