Adding more methods to Parameters

[germa89]

I have been thinking a bit about this.

I personally believe this subclassing is the right way.
And although it is not need because most of the important methods, probably this subclassing can add something else we are missing now. So I would like to go ahead with this.

Actually better not.

One thing is the underlying dict _parm which stores the mapping, and another thing is the API to that dict which is this class.

To be fully consistent, inheritate this from dict will imply to get rid of _parm and use the underlying class to store everything.
It can be done, but i don't think it is worth our time right now.

@germa89 agree with the choice. You can make it feel like a dict without subclassing and that's typically a better choice. The number of methods you have to implement is not that large
