Overview

todo: move these methods to the ‘WikiLink’ classes…?

this class is responsible for answering any questions related to jekyll markdown documents that are meant to be processed by the wikilinks plugin.

the following methods are specifically to address two things:

1. ruby's 'find' / 'detect' function does not throw errors if 
   there are multiple matches. fail fast, i want to know if there
   are duplicates. 
   (not using sets because i don't want to clobber existing documents)
2. handle all jekyll documents in one place. i don't want to
   have to filter all documents for target markdown documents 
   every time i need to check if a file exists.

there is probably a better way to do this…i would prefer to have a plugin-wide function that just wraps all of this and can be called from anywhere in the plugin…but ruby is not a functional language… gotta have classes…
