Sun Apr 27 10:32:40 2014 +0200 Emmanuel Garette <egarette@cadoles.com>
* add dynamic ChoiceOption:
we can have dynamic ChoiceOption. Parameter values can be a function
and as callback, we can add values_params
Fri Apr 25 22:57:08 2014 +0200 Emmanuel Garette <egarette@cadoles.com>
* add SubMulti:
a SubMulti is a multi in a multi variable
