/**     No leaf index can have a value of 0x0000.  The leaf indices are
 *      separated into ranges depending upon the use of the type record.
 *      The second range is for the type records that are directly referenced
 *      in symbols. The first range is for type records that are not
 *      referenced by symbols but instead are referenced by other type
 *      records.  All type records must have a starting leaf index in these
 *      first two ranges.  The third range of leaf indices are used to build
 *      up complex lists such as the field list of a class type record.  No
 *      type record can begin with one of the leaf indices. The fourth ranges
 *      of type indices are used to represent numeric data in a symbol or
 *      type record. These leaf indices are greater than 0x8000.  At the
 *      point that type or symbol processor is expecting a numeric field, the
 *      next two bytes in the type record are examined.  If the value is less
 *      than 0x8000, then the two bytes contain the numeric value.  If the
 *      value is greater than 0x8000, then the data follows the leaf index in
 *      a format specified by the leaf index. The final range of leaf indices
 *      are used to force alignment of subfields within a complex type record..
