#1 Deep zooming.

[Jason McGuiness]

It would be nice to really "deep zoom" with huge
magnifications, > say, "double" can support. This
requires:

1. Arbitrary precision "integers" (largely done, "integer.h
& cpp"), "reals" (less done, "double.h & cpp"). In the
AML.
2. Detection of excessive zooming in the "Fractal
Generator" - done.
3. Implementation of switching the underlying number
system, or fractal type to the arbitrary-precision type.
This is tricky - do the number s all inherit from a
base "number" and you use polymorphism to change
the base number type within the Fractal Type in the
Fractal Generator, do is each fractal type implemented
with the arbitray-precision arithemtic, thus doubling the
numbers of Fractal Types to implement? How would this
duplication be nicely shown to the user, in a non-
confusing manner? Also should all of the number types
in the AML become templated to allow them to be
implemented with different underlying
int/double/integer/real types? How will this affect the
(broken) templater in VC++v6.0sp5? (The "Thread.hpp"
file already is a source of much grief in this matter.)

Some work done on this!
Integer type:
- Extended right-shift and added left-shift operators.
Real type:
- Started to implement more of the "real" type. (Actually
in "real.h" & "real.cpp".)
- Added simple arithmetic, +, -, /, * & raise to an integer
power.

Added these operators to the custom expression generator
for playing with and testing.
