improved formatting for docs -- these were in pod sections but were all
formatted as verbatim sections, and i moved them into normal paragraphs,
lists, etc. should make things more readable from the web.

Adds a new context that is more limited by not allowing operations
within the coefficients and exponents themselves. Access this context
using
Context("LimitedPolynomial-Strict");

Move the context creation to the _init routine so that modifications
to main:: occur at initialization time, not when the file is loaded.

Normalized comments and headers to that they will format their POD
documentation properly. (I know that the POD processing was supposed
to strip off the initial #, but that doesn't seem to happen, so I've
added a space throughout.)

Extended this context to handle multivariable polynomials. So you can
use things like
loadMacros("contextLimitedPolynomial.pl");
Context("LimitedPolynomial")->variables->are(x => 'Real', y => 'Real');
Context()->flags->set(singlePowers=>1);
$f = Formula("1 + x + y + 2xy + x^2 + y^2");

Fixed a problem where things like x+4x would be accepted even in
single-power mode (the initial x was not being identified as a single
power of x correctly).

Make error messages potentially localizable (by making them use
sprintf-style strings rather than variable subtitution).

Implements a Parser context in which only polynomials (of a single
variable) can be entered. Only sums of multiples of powers of the
variable are allowed to be entered (though the coefficients can
contain mathematical operations). An optional flag lets you specify
that only one term of each degree is allowed, so the student would
have to combine 1+x+x+x^2 to get 1+2x+x^2 in that case.
This form allows you to request diffs between any two revisions of this file.
For each of the two "sides" of the diff,
enter a numeric revision.
