Detailed Description

Simple class that represents an equation.

It does not do any calculation, it serves only as a helper to write equations like $ 7 xy + 3 y^2 - 5 x - 2 y + 8 = 0 $ in a pretty form. It can handle equations of max two variables (named x and y ) with no limits on the grade of the terms. (well, the limit is 15, but I doubt anyone will ever use such a factor for a power...)
