Changed posttrans array to an object, as key-value pairs made more sense than value-value pairs.
Changed name of posttrans object to intoout, as this better describes the intention of the object--to show how certain words in the input should appear in the output.
Created initialisation method called parseIo() which creates a search pattern based on intoout keys. This is then used later to make substitutions in output from Beth.
Updated version to 0.0.4. Hotfix applied should fix #9.
Merge branch 'hotfix-0.0.4'
