Renamed file to be less long.
Deleted all legacy bash references for creating various types of Nimzo controllers. This has now all been simplified into a single file.
Got rid of legacy file (the hacky one) which created/removed Nimzo content + changed 'rewrite' to 'write' in content writer so when typing into the command line, the 'R' can be reserved for 'run-tests'. Saves typing 'ru..' every time when using TAB to autocomplete.
