Add params_like :method

[Pajk]

Now there is 'see :method' available in DSL, it maybe does make sense to use it in few cases but much more helpful feature would be the possibility to say 'method A has same parameters as method B'. Almost every #update method has same params as #create method.

Possible solution:

api :PUT, '/resource'
params_like :create
def update; end

When asking for #update parameters description, apipie would take those from #create method.

Or maybe param group. Let's say

param_group :person do
  param :first_name
  param :last_name
end

That explicitly states that this list is meant to be shared which is not so obvious, when using the params_like: in your case, I can imaging the situation, that new param will be added for create method, but the author doesn't realize, that this will cause also updating the update documentation.
