Labeled tuples

Finished up statics and dynamics for labeled tuples types/expressions, will work on patterns and projections later in the project. As I was looking further at the code, I need to work more on the core code for actions and cursors before moving onto the front end. I would appreciate feedback on the statics/dynamics code though.

Nice work @ecdeuts, but closing due to haz3l having a different approach to parsing that will likely allow us to approach the design differently.
