Need to support alternative spellings of principal parts with varying frequencies?

confirmed that we need to do this. will require some rethinking of the data model for the Lemma. May need to break out principal parts into their own model element so that we can apply features to them.

alternatively, we could change Lexeme to support multiple Lemma objects, which seems to be more reflective of the parser output, but would have a more drastic impact on the code.

I have decided to address this by adding an altLemmas property to the Lexeme data-model object which can be used to add alternative lemmas for a single lexeme. Based upon my understanding of a Lexeme (https://en.wikipedia.org/wiki/Lexeme) this is the most accurate representation of the scenario we need to support. Different dictionaries have different ways of representing a single distinct lemma.
