GetDirections form element

I have a recommendation for Drupal 7 version of this module.
As you know Drupal 7 now has rendering api and we've already have form arrays before
By turning getdirections into a custom form api instead of a standalone form and some theme functions
It will become possible to easily integrate getdirections to any custom form,
Also it also fixes one one of the limitations for getdirections which is the fact that only
one getdirections can be used on each page (duplicate ids and element names)
