Changed HttpClientHelper accessor method to only return a new instance
instead of using a static one.
Added a couple new classes to help with building an initial distance
DB.
Added classes/functionality to interact with Google Maps distance API.
Removed the PostGresQLTest class, combining it into the
TransQGoogleInterogator class.
Querying 'CD'.com works. Requesting distances from ggle maps
works. 
WS created for requesting quotes using CD.com. 
Need to create a client for the WS & a way to use it (form).
