Add a controller for composite controls; this is used
to flag contained controls as required when they have
been partially filled in (to treat entering one of two
such fields as invalid.) WTD-593.
Implement date time controls up to the point that
they validate, and information (albeit not the right
information) propagates back up to the containing
form. WTD-530.
Add remaining platform form controls; amend mct-form
and mct-control directives to better communicate state.
Begin working on problem of communicating validation
back out of the form. WTD-530.
Initial minimal working implementation where a
two-way binding between form and form user is
observable.
Notably, change ng-options to options, since
ng-options is terminal (it breaks mct-control).
WTD-530
Bring in previous work on the forms component; this includes
transitioned versions of specific form elements, and the
mct-form direction which generates these. WTD-530
