# xxx painful, but... 
# bootstrap3 requires the <input> fields to be tagged class='form-control'
# my first idea was to add this in the view template of course, BUT
# I can't find a way to access the 'type=' value for a given field
# I've looked rather deeply out there but to no avail so far
# so as we have a demo coming up soon, and until we can come with a less intrusive way to handle this...
