Arthur Ganger / Braille_In

This is a *VERY* Rough library for translating binary representations of grade 1 braille into ASCII strings.

Braille_In.cpp@3:36f07cfb3fe1, 2012-10-12 (annotated)

Parent:

Added  overload of translateBraille  to allow passing const char * so that c++ strings may be used with .c_str() syntax. I'm sure there's a more clever way to handle that than just duplicating the function, but it's late and my deadline is tomorrow:)
