[Parameter] Getting parameter from a Node recquire difficult cast

Issue

Getting a parameter from a Node is currently quite tedious:

float epsilon = std::static_pointer_cast<BatchNorm_Op<2>>(batchnorm->getOperator())->get<float>("Epsilon");

The biggest issue I see is that we need to cast to a templated type. This is mostly due to Operator not inheriting from Parametrizable and thus not having the get() method in its declaration.

Solutions

• Invert Node -> Operator hierarchy in the user interface (see #15)
• Add in Operator a trampoline method which calls the Parametrizable.get<T> method.

I think a simple solution would be to make a base (pure virtual) Parameterizable class with setter and getter, that could be common of Parameter and CParameters (GenericOperator).

Done in !16 (merged)

Now we need to Make Operator inherit of Attribute.

Once done, a refactor would be needed to remove the use of cast.
