How to let user name reactors with hierarchy maintained in the name. This would also enable to have a unique name for each reactor.

• With this PR name would be a keyword (the way bank_index is) that could be used to build a FQN of a reactor
• Default name of the reactor would be used if user doesn't provide name when instantiating a reactor instance
• a = new [2] A(name = "A"); Two banked instances of A would have names A0 and A1
• If parent reactor of A also has a name parameter, it would be used while building a name for A (Base0.C0.B0.A0, Base0.C0.B0.A1, Base0.C0.B0.A2 would be the names of A instances part of Bank-0 B instance and Bank-0 C instance)
