Output path handling overhaul (all modules)

[sfneal]

Create a class (possibly a global?) that is capable of handling and generating output paths for any file type. It seems as if similar code is used for almost all of the pdf.conduit modules so that can likely be replaced with a class or function call. Further, not every module has the ability to specify an output directory at this time.

Create directory if it does not exist should be one of the features.
