New LID defaults for EPA SWMM 5.1.008 - from the SWMM 5 code

  8 Types of LID's

ProcessTypesLong: array[0..7] of String =                                    //(5.1.008)

    ('Bio-Retention Cell', 'Rain Garden', 'Green Roof',
     'Infiltration Trench', 'Permeable Pavement',
     'Rain Barrel', 'Rooftop Disconnection', 'Vegetative Swale');              //(5.1.008)
   ProcessTypesMedium: array[0..7] of String =
