Sixtypical Compilation

This is a test suite, written in Falderal format, for compiling Sixtypical to 6502 machine code.

-> Functionality "Compile Sixtypical program" is implemented by
-> shell command "bin/sixtypical --compile %(test-body-file) | fa-bin-to-hex"

-> Tests for functionality "Compile Sixtypical program"
