PISDK Architecture for Gen Apps

• One PI Module for the Generation portfolio
• A sub-module of the Portfolio Module corresponds
  to a Generation Unit.
• A Unit Module corresponds to a Unit class.
• Various Unit Parameters form the
  aliases/properties of the unit module and are
  accessed that way from the code.
• Very easy to add/delete units from the portfolio.
