Format path loops

[nicholasdelrio]

Need to ensure that nobody registers a sequence of operators that forms a loop. In the future, I can be smarter about the loops and allow them under certain circumstances (don't know these circumstances yet). For now, I just want to check for a loop and if one exists warn the user or nix the path.

Are you saying that we cannot register both 'JPEG2GIF' and GIF2JPEG'? Not
good :-) This restriction is something you may enforce locally. I doubt
one can enforce it globally.

Cheers,
Paulo.

You are absolutely correct, not good! I can set some checks in the code to make sure the pipeline generator doesn't do something silly like building a pipeline such as (JPEG2GIF -> GIF2JPEG -> JPEG2GIF ....)
