Prepare to move functionality from Order to Parser
WIP: Setup simple order parser tests

* Leaving Order and order_spec alone for time being
* Parser returns a hash, will eventually return order

Still debating Parser interface:
  Parser.parse('A Par S A Mar-Bur') or Parser::parse(A Par S A Mar-Bur)
Add Parse simple MOVE order

-Specs added
-need to go back and clean up implemenation

Still struggling with design of class Parser, should this thing be a module?
