Checkpoint 8

/*
Your challenge is this: make a protocol that describes a
  building, adding various properties and methods, then 
  create two structs, House and Office, that conform to it.
 
Your protocol should require the following:
    A property storing how many rooms it has.
    A property storing the cost as an integer 
      (e.g. 500,000 for a building costing $500,000.)
    A property storing the name of the estate agent 
      responsible for selling the building.
    A method for printing the sales summary of the building,
     describing what it is along with its other properties.
