Source code for ship.fmp.datunits.orificeunit

"""

 Summary:
    Contains the OrificeUnit type classes.
    This holds all of the data read in from the orifice units in the dat file.
    Can be called to load in the data and read and update the contents 
    held in the object.
    
    The OutfallUnit is also in here. It has the same setup as the OrificeUnit
    so it subclasses orifice.
