randomShellableIdealChain -- Produces a chain of ideals from a random shelling

Usage:

L = randomShellableIdealChain(R,m,k)

L = randomShellableIdealChain(R,m)
Inputs:
- R, a ring, a polynomial ring
- m, an integer, dimension of the facets in the shellable complex
- k, an integer, the degree of the smallest ideal
Outputs:
- L, a list, list of Stanley-Riesner ideals of the simplicial complexes of the truncations of the shelling.

Description

i1 : R = ZZ/101[x_0..x_3];

i2 : L = randomShellableIdealChain(R,1)
