*   This program reads the Franctional UCA table and generates
*   internal format for UCA table as well as inverse UCA table.
*   It then writes binary files containing the data: ucadata.dat 
*   & invuca.dat
*   Change history:
*   02/23/2001  grhoten                 Made it into a tool
*   02/23/2001  weiv                    Moved element & table handling code to i18n
*   05/09/2001  weiv                    Case bits are now in the CEs, not in front
