Complete version history
========================

2007-04-17 1.12 Tels 182 tests 
  * speed up fibonacci():
    + by not making the argument a BigInt
    + caching a few more numbers
    + removing a few needless scalar computations
  * fix bug in fibonacci() missing a few intermidiate results
  * euler() just uses BigInt's fast bexp() method and is thus now MUHC faster
  * require Math::BigInt v1.83 (and thus Perl v5.6.2)
  * bundle and use Module::Install

		 some more tests
2003-12-11 1.09 Tels 
 * require Math::BigInt v1.67 
 * factorial() uses simple BigInt bfac() for speed
2004-08-13 1.10 Tels 161 tests 
 * __END__ in Big.pm, remove shebang line
 * removed needless return statements for more speed
 * log() now simple calls BigFloat log for speed (it was unusable
   slow before)
 * hailstone() is between two and three times faster
 * pi() is slightly faster by caching two objects for '5' and '236'
 * require Math::BigInt v1.72
 * arctan(), tan(), sin(), cos() etc are now about 10% faster
 * arcsin($x) were $x != 0 was broken

2005-01-02 1.11 Tels 177 tests 
 * streamlined euler()
 * @k = hailstone() is about 3..4 times faster
 * $k = scalar hailstone() is about 6..7 times faster
 * primes() is about 1.5 times faster
 * fix documentation for primes() (Thanx Es Allen Smith!)
 * add to_base($n, $base, [$alphabet]) (Thanx Tilghman Lesher!)
