Create a helper library to create a distributed representation for documents

[liadmagen]

Create python script as a helper-library that can convert a document to a distributed representation vector (using word2vec, GloVe, fastext, etc.)

If possible, it can be nice to have different methods implemented to have a good comparison of them.

The functions in the library will receive a string (document as a text) and optional method (algorithm to use) and will output the vector representation of the document, using that method.
