1.2.0 FINAL

Repositioned some functions in the physics library, improved the event
model, added some functions (with events) to prompt for user input and
to cast some string to a scalar (more maybe to follow). Improved the
documentation and some numeric algorithms. Improved the parser and added
some functions like the Faddeeva function. Improved the existing plot
values and the loading process.

YAMP 1.2.1 Start

Extended documentation with the possibility of an external link (mostly
to wikipedia). Improved the Mandelbrot function and added other
functions for creating fractals. Improved arcsin, arctan, ... - and
added functions for csc, sec, csh, sech and hyperbolic versions. Added
more kind of functions and already separated them. Improved the parse
engine.
YAMP 1.2.2 second

Fixed a bug in the number expression concerning exponential notation.
Added more Wiki-Links, improved the visualization function and changed
some return types to "void". Fixed a bug in the laplace distribution and
improved the "variable change" event (did not catch expanding matrices).
Improved the subplot to use the ChangeLastPlotTo function and created
the new setdef function for templating plots.
YAMP 1.2.1 maybe final

Improved the parser (fixing some bugs that cause severe exceptions),
improved error reporting, added functions for obtaining a list of
symbols, added a function to define default values for plots, improved
statements, added the surfaceplot with mesh, surf and meshgrid
functions. Improved documentation and made YAMP more robust.
YAMP 1.2.1 immediate bugfix

Fixed a bug with the operator hierachy. Also improved the surface and
mesh functions.
YAMP 1.2.1 final commit

Improved constructors of elementary expressions, improved increment and
decrement operators, included eval function and fixed some minor bugs.
YAMP 1.2.2 (First)

Improved Physics package (Polygamma, Polylog finished), improved
Gegenbauer function, Spence and Ylm.
Using C# version of BLAS for multiplication (speedup of 50 to previous
version), improved zeta and gamma function. Added properties to heatmap,
scalar and matrix values. Added Hurwitz zeta, log2, log10 and sphere
function. Started work on plot annotations.
YAMP 1.2.2 final commit

Added let keyword, added conversion functions and added some fitting
functions / helpers.
Updated portable projects to 1.2.2 final
Explicitly used ManualResetEvent handle in PropmptFunction to ensure portability
