Added -R test to string tests for functions that pass work to string_FormatCase.
Renamed file.
Forgot to delete the old file.
Updated the readme with a support section to advise others to help if they can.  If I'm the only one who ever writes on this system, it will only ever be as effective as I am.
Prefixed all variables (except exit codes, because Docker reads those) with an underscore.  This enforces the idea of globals being __SBT_something and lexically scoped variables to functions like so: _something.  This fixes #4 and should prevent confusion for end-users later.
