v0.6.0-alpha

• Feature - Yaml module now maps simple scalar sequences to metadata when flattening

• Feature - Added new Documents module that replaces the documents in the pipeline with alternate ones

• Feature - IDocument now implements IMetadata so metadata can be retrieved directly from the document object
• Feature - Added a .String(...) method to IMetadata to make getting string values easier
