Partial Implementation of Creating Contacts

This implementation is being listed as "partial" because even though I
have contact fully implemented and a test ready for it, I have to create
a customer before I can create a contact and make sure the tests pass.

In WWW::LogicBoxes
  Modified to consume WWW::LogicBoxes::Role::Command::Contact

Created WWW::LogicBoxes::Contact
  Has the same data types and required fields as defined by the
  LogicBoxes API for all attributes

Created WWW::LogicBoxes::Role::Command::Contact
  Implemented create_contact (Test is not yet passing)

In t/04-contact.t
  Implemented tests for use case "Create a US Contact"
