  /*
  To add a new enum type
        (For example: UShoeSize  with values USHOE_WIDE=0, USHOE_REGULAR, USHOE_NARROW, USHOE_COUNT)
  
      0. Make sure that all lines you add are protected with appropriate uconfig guards,
          such as '#if !UCONFIG_NO_SHOES'.
      1. udbgutil.h:  add  UDBG_UShoeSize to the UDebugEnumType enum before UDBG_ENUM_COUNT
        ( The subsequent steps involve this file, udbgutil.cpp )
      2. Find the marker "Add new enum types above this line"
      3. Before that marker, add a #include of any header file you need.
      4. Each enum type has three things in this section:  a #define, a count_, and an array of Fields.
         It may help to copy and paste a previous definition.
      5. In the case of the USHOE_... strings above, "USHOE_" is common to all values- six characters
           " #define LEN_USHOE 6 "
         6 characters will strip off "USHOE_" leaving enum values of WIDE, REGULAR, and NARROW.
      6. Define the 'count_' variable, with the number of enum values. If the enum has a _MAX or _COUNT value,
          that can be helpful for automatically defining the count. Otherwise define it manually.
          " static const int32_t count_UShoeSize = USHOE_COUNT; "
      7. Define the field names, in order.
          " static const Field names_UShoeSize[] =  {
          "  FIELD_NAME_STR( LEN_USHOE, USHOE_WIDE ),
          "  FIELD_NAME_STR( LEN_USHOE, USHOE_REGULAR ),
          "  FIELD_NAME_STR( LEN_USHOE, USHOE_NARROW ),
          " };
        ( The following command  was usedfor converting ucol.h into partially correct entities )
        grep "^[  ]*UCOL" < unicode/ucol.h  |
           sed -e 's%^[  ]*\([A-Z]*\)_\([A-Z_]*\).*%   FIELD_NAME_STR( LEN_\1, \1_\2 ),%g'
      8. Now, a bit farther down, add the name of the enum itself to the end of names_UDebugEnumType
            ( UDebugEnumType is an enum, too!)
          names_UDebugEnumType[] { ...
              " FIELD_NAME_STR( LEN_UDBG, UDBG_UShoeSize ),   "
      9. Find the function _udbg_enumCount  and add the count macro:
              " COUNT_CASE(UShoeSize)
     10. Find the function _udbg_enumFields  and add the field macro:
              " FIELD_CASE(UShoeSize)
     11. verify that your test code, and Java data generation, works properly.
