+2007-07-30 Reorganized configuration code to work with traited config
+ objects. The new config system is located in the
+ matplotlib.config package, but it is disabled by default.
+ To enable it, set NEWCONFIG=True in matplotlib.__init__.py.

to make collection kwargs agree with setter names, so
updating works; related minor cleanups.

Revision: 3631
http://matplotlib.svn.sourceforge.net/matplotlib/?rev=3631&view=rev
Author: mdboom
Date: 2007-07-30 09:41:53 -0700 (Mon, 30 Jul 2007)
Log Message:
-----------
Major refactor to separate out backend-specific stuff from
fontset-specific stuff. What used to be the Fonts class heirarchy is
now both a Fonts heirarchy and MathtextBackend heirarchy. This should
be further improved in the future when the backends themselves are
refactored to be more consistent.
Now uses the multi-sized delimiters in the BaKoMa fonts. This
prevents the square root symbol from getting overly wide as it gets
tall. (As auto-sized parens, brackets and braces etc.)

+#
+# Quantum Mechanical Simulation using Finite-Difference
+# Time-Domain (FDTD) Method
+#
+# This script simulates a probability wave in the presence of multiple
+# potentials. The simulation is c arried out by using the FDTD algorithm
+# applied to the Schrodinger equation. The program is intended to act as
+# a demonstration of the FDTD algorithm and can be used as an educational
+# aid for quantum mechanics and numerical methods. The simulation
+# parameters are defined in the code constants and can be freely
+# manipulated to see different behaviors.
+#
+# NOTES
+#
+# The probability density plots are amplified by a factor for visual
+# purposes. The psi_p quanity contains the actual probability density
+# without any rescaling.
+#
+# BEWARE: The time step, dt, has strict requirements or else the
+# simulation becomes unstable.
+#
+# The code has three built-in potential functions for demonstration.
+#
+# 1) Constant potential: Demonstrates a free particle with dispersion.
+#
+# 2) Step potential: Demonstrates transmission and reflection.
+#
+# 3) Potential barrier: Demonstrates tunneling.
+#
+# By tweaking the height of the potential (V0 below) as well as the
+# barrier thickness (THCK below), you can see different behaviors: full
+# reflection with no noticeable transmission, transmission and
+# reflection, or mostly transmission with tunneling.
+#
+# This script requires pylab and numpy to be installed with
+# Python or else it will not run.

Lots of sizing and layout tweaks. Support $\sqrt[3]{foo}. The line
meets up with the check mark rather clumsily on the Agg backends due
to rounding errors and lack of subpixel placement... will look into that.

+ with an even number of $'s (non-escaped) will be sent to
+ the mathtext parser for layout.
+
+ - Sub/superscripts are less likely to accidentally overlap.
+
+ - Support for sub/superscripts in either order, eg. $x^i_j$
+ and $x_j^i$ are equivalent.
+
+ - Double sub/superscripts (eg. $x_i_j$) are considered
+ ambiguous and raise an exception. Use braces to disambiguate.
+
+ - $\frac{x}{y}$ can be used for displaying fractions
+
+ - $\left(\frac{x}{y}\right)$ may be used to create
+ parentheses and other delimiters that automatically
+ resize to the height of their contents.
+
+ - Spacing around operators etc. is now generally more like
+ TeX.
+
+ - Added support (and fonts) for boldface (\bf) and
+ sans-serif (\sf) symbols.
+
+ - Log-like function name shortcuts are supported. For
+ example, $\sin(x)$ may be used instead of ${\rm sin}(x)$
+
+ - Limited use of kerning for the easy case (same font)
+
+ Behind the scenes, the pyparsing.py module used for doing
+ the math parsing was updated to the latest stable version
+ (1.4.6). A lot of duplicate code was refactored out of the
+ Font classes.
+

2007-07-19 completed numpification of most trivial cases - NN
2007-07-19 converted non-numpy relicts troughout the code - NN
