Text transformation class/package

[duggurd]

Should probably consider creating a module/package that exclusively focuses on doing transformations on text as large parts of our project is using some form of transformation on text. Therefore probably best to have a unified and generalized approach to doing the transformations in a module or package.

Add fucntionality so it calculates the weight of a certain transformation, us crofiling to get some metrics for example.
