Release Notes:

Release 0.5 (5/3/10) - Added absolute values, inequalities and ranges.

Release 0.4 (1/26/10) - Alvigra now solves quadratic equations.

Release 0.3.1 (1/15/10) - Added in factoring, including factoring quadratics.  Also cleaned up the equation display quite a bit.

Release 0.3 (12/31/09) - Added square roots.

Release 0.2.1 (11/04/09) - Added side swaps and term cancellation to get to some solutions with fewer steps.  Added icons for buttons (complete with hints) and got rid of menu options that aren't usable from the web.  Also some minor bug/usability fixes.

Release 0.2 (10/21/09) - First release to actually solve equations (previous release could only simplify equations).  Also added in ability to save off equations with their solutions to facilitate regression testing (a great time save since I have a suite of over 35 equations to use as test cases and I can now run them all in less than a minute whenever I make a change).

 Release 0.1 (Nov, 08) - First partial beta released on the web.  Could only simplify expressions, not solve them.
