Updated the indent command execution module to reflect that failing compilation may cause additional indent errors. Also changed the name of the test so it is less likely to be confused with the style check sub test for indentation/spacing.
Eliminated string literals of g++, better to use the compiler variable that will eventual be set in config
Complete rework on indentation block spacing check.  Logic is the same but pieces are put in better places and alrogithm/variables make more sense.  Now uses a Blocks object as well.  Closes #23. Also expanded tabs prior to adding lines to a block. Closes #27
