This initial commit adds routing to search results from a search

Helper classes and methods for doing the heavy lifting
HTTPXMLRequest wiring and piping.
SAX Document and Parsing
Very basic Airport locations finder, which we will ultimately get from
a service.
Backing Model
A basic mock response to use while in stealth mode and development
trial and error to not hit live services.
A rudimentary display of results.  Each div can be packed up with data
and prettied up.
