Repository template - rename add method to save

[MrYamous]

Hi,

Few times ago, PR #939 added new add and remove methods in repository template

I recently had the opportunity to use them, and when i made a method to edit a resource in my controller i was like "where is the method to edit ?" and then i realize add can do the job but i think it's a confusing name.

What would you think about rename this add method to something more generic like save ?

Hi @bdaler
As contributor of the concerned PR, do you have any advice about this ?
