Revision history for Perl extension Math::Symbolic.

0.108  Wed Jul 16 22:41:01 2003
	- Added Math::Symbolic::Compiler (as a modified to_sub.pl).
	- Modified value() semantics to optionally take arguments.
	- Added set_value() method.
	- Added lots of docs.
	- Added some tests.

0.107  Sun Jul 13 21:25:29 2003
	- Fixed tests. (Note to self: recreate MANIFEST for dists.)

0.106  Sun Jul 13 19:56:29 2003
	- Modified the parser to parse unknown identifiers as variables.
	- Modified Operator constructor to send operands through the parser
	  if they aren't valid Math::Symbolic::* objects.
	- Added and fixed docs. A lot.
	- Added tests.

0.105  Wed Jul  9 18:56:33 2003
	- Added several important items to the TODO.
	- Accepted the fact that the TODO is growing faster than the code base.

0.104  Sat Jul  5 19:17:00 2003
	- Added to_sub.pl to the distribution. (Math::Symbolic -> Perl sub
	  compiler.) This is just a proof-of-concept.

0.103  Thu Jun  26 15:08:12 2003
	- Fixed test errors.
	- Added (very little) documentation.

0.102  Wed Jun  25 21:04:41 2003
	- Added overloaded interface for arithmetic operators, exp, log,
	  sqrt, boolean context, numerical context, sin, cos, mutators.
	- Added tests.
	- Added docs.

0.101  Fri Jun  20 15:45:10 2003
	- Documentation fixes

0.100  Fri Jun  20 01:32:32 2003
	(Yep, I hack at random hours.)
	- Implemented hyperbolic sine, h cosine.
	- Implemented partial derivatives for h sine, h cosine
	- Amended parser for h sine, h cosine.
	- Same for tangents
	- Myriad of bugfixes
	- ExportConstants now includes (and exports) PI and EULER constants.
	- Renamed class data in M::S::Operator.
	- Cotangent.
	- Arc sine, arc cosine, arc tangent, arc cotangent.
	- Hyperbolic area sine, h. a. cosine
	- Tests for the above.
	- Broke the parser badly.
	- (much later) Fixed it again.
	- Some more documentation
	- Renamed test files
