Constructor Details
#initialize(name = :"", systemT = nil, &ruby_block) ⇒ Scope
Creates a new scope with possible +name+. If the scope is a top scope of a system, this systemT is given by +systemT+.
The proc +ruby_block+ is executed for building the scope. If no block is provided, the scope is the top of a system and is filled by the instantiation procedure of the system.
