#4 Generic Lens plug-in

The idea is to create a very generic lens plug-in, with
a function z = f(x, y) describing the lens, and Snell's
to calculate the position of the original picture.

We can use the same trick here as in the Splitter plug-in to
use the built-in C# compiler in .NET and on-the-fly generate
code from the formula.
