  v0.06  -- Sped up the s_mp_add, s_mp_sub which inturn sped up mp_invmod, mp_exptmod, etc...
         -- Cleaned up the header a bit more
         
  Dec 30th, 2002
  v0.05  -- Builds with MSVC out of the box
         -- Fixed a bug in mp_invmod w.r.t. even moduli
         -- Made mp_toradix and mp_read_radix use char instead of unsigned char arrays
         -- Fixed up exptmod to use fewer multiplications
         -- Fixed up mp_init_size to use only one heap operation
            -- Note there is a slight "off-by-one" bug in the library somewhere
               without the padding (see the source for comment) the library 
               crashes in libtomcrypt.  Anyways a reasonable workaround is to pad the
               numbers which will always correct it since as the numbers grow the padding
               will still be beyond the end of the number
         -- Added more to the manual
         
  Dec 29th, 2002
  v0.04  -- Fixed a memory leak in mp_to_unsigned_bin
         -- optimized invmod code
         -- Fixed bug in mp_div
         -- use exchange instead of copy for results
         -- added a bit more to the manual
         
  Dec 27th, 2002
  v0.03  -- Sped up s_mp_mul_high_digs by not computing the carries of the lower digits
         -- Fixed a bug where mp_set_int wouldn't zero the value first and set the used member.
         -- fixed a bug in s_mp_mul_high_digs where the limit placed on the result digits was not calculated properly
         -- fixed bugs in add/sub/mul/sqr_mod functions where if the modulus and dest were the same it wouldn't work
         -- fixed a bug in mp_mod and mp_mod_d concerning negative inputs
         -- mp_mul_d didn't preserve sign
         -- Many many many many fixes
         -- Works in LibTomCrypt now :-)
         -- Added iterations to the timing demos... more accurate.
         -- Tom needs a job.       
  
  Dec 26th, 2002
  v0.02  -- Fixed a few "slips" in the manual.  This is "LibTomMath" afterall :-)
         -- Added mp_cmp_mag, mp_neg, mp_abs and mp_radix_size that were missing.
         -- Sped up the fast [comba] multipliers more [yahoo!]
  
  Dec 25th,2002
  v0.01  -- Initial release.  Gimme a break.
         -- Todo list, 
             add details to manual [e.g. algorithms]
             more comments in code
             example programs
