/*
 * TYPEDEF: SE_REFERENCE_SYMBOL_COMPARE_FUNCTION_SIGNATURE
 *
 *   A short-hand way for a user to declare a user-defined compare
 *   function for use with reference symbols that have been created
 *   using user-defined data.  This type declaration ensures that the
 *   function will have the desired function signature.
 *
 *   The comparison function must be defined to accept the following
 *   parameters in this order:
 *   1) a const pointer to a block of user-defined data, call it a_ptr
 *   2) a const pointer to a block of user-defined data, call it b_ptr
