Move some map setup into support file
Add attribute-to-form translator

Slightly more complex than the form-to-attribute translator, this
should allow for internal values to be detected without more than
a fairly simple override.  Complex tests and docs coming soon....
Add test for verifying blank attribute behavior
Add test for overriding SingleAttributeTranslator
Add documentation on attrs-to-form translation
Add links to examples
Merge branch 'feature/attributes-to-form'
Bump to 1.2.0

Added new translator to give a full two-way translation
Add round-trip specs

Verifies the two translators work together as expected, and can both
use the same map hash
