Iterate over boilerplate.yml defined variables

[matiri132]

It would be nice to have the capability of iterate over the variables defined in the boilerplate.yml file, to give the capability to access dynamically to each of it. We are looking for a way to create code inside the templates files depending on the existence of a variable and not accesing by it's name directly.

As a solution I propose a way to access directly to the variables map to get the variable name as a key of each element in the map.
