/** @file expand_subs.cpp
*
* The first test routine implements Denny Fliegner's quick consistency check:
* e = (a0 + a1 + a2 + a3 + ...)^2
* expand e
* substitute a0 by (-a2 - a3 - ...) in e
* expand e
* after which e should be just a1^2.
* In addition, a simpler modification is tested in the second test:
* e = (a0 + a1)^200
* expand e
* substitute a0 by -a1 in e
* after which e should return 0 (without expanding). */
