Refactoring property locators.

Turning iterator (for_each) into a property locator.
Integration specs are failing. Need to refactor Parser
since it doenst have select_nodes and locate methods anymore.
Need to refactor the DSL to support new iterator format.
Need to get rid of Crawler#for_each and move that logic into
a property factory.
