This has been moved to playdoh itself

 - added --dirname feature
 - refactored the Template and entry point

I dont want to rewrite this :( that'd make me feel like a terrible person.

I want to make small incremental improvements to it.

I guess i can just leave this as is and "abandon" it and then just fork and rebrand this somewhere else.
