#2205: Implemented review comments

  • made Node and Network abstract
  • renamed GenericNode to UserDefinedNode and sealed it
  • added sealed UserDefinedNetwork
  • made Nodes in Network not changeable by default
  • made Parameters in ParameterizedPort not changeable by default
  • removed value None in PortParameterType
  • refactored call algorithm.PrepareMessage() in AlgorithmNode
