/*
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.
