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

2002-08-13 1.08: pi() finally works (thanx to Robert Jaeger)
require BigInt v1.61
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!)
