This program displays a square box and fills it with a number of randomly
positioned and oriented elliptical clasts whose aspect ratio is specified by
the user. It then progressively deforms the box according to parameters
specified by the user (pure shear, simple shear, and number of steps),
translating and rotating the clasts (Jeffery model rotation) to generate a
strain fabric.

To start a deformation, click the "New Deformation" button and input
your desired parameters. The program will display an undeformed box.
Left-click anywhere in the window to take the deformation forward one step,
and right-click (or ctrl-click) anywhere in the window to take the deformation
backward one step. At any time, you can click "New Deformation" again
to start over.

Shear Fabric should run on any computer with Java 1.4.2 or later installed,
but the author makes no guarantees. Furthermore, the author is not
responsible for any damage or loss of data caused by running Shear Fabric
(though the odds of anything untoward happening are quite miniscule).

Feel free to use Shear Fabric in a classroom setting and distribute it to
students and colleagues. (They are its intended audience, after all.) 
In any other circumstances, do not distribute Shear Fabric without the
express permission of the author.

VERSION HISTORY
1.0 - Initial Release
1.1 - Added the ability to step backwards through the deformation, fixed a few
math bugs, made some positive cosmetic changes
1.2 - When starting a new deformation, Shear Fabric now retains the input values
from the previous deformation, making repeated simulations easier to perform
1.2.1 - Minor changes to help text
