cartanEilenbergResolution -- Computes free resolution of a ChainComplex

Usage:

m = cartanEilenbergResolution C
Inputs:
- C, a chain complex,
Optional inputs:
- LengthLimit => ..., default value infinity, How many steps to compute
Outputs:
- m, a chain complex map, surjective quasi-isomorphism from a free ChainComplex

Description

Uses a different algorithm than resolutionOfChainComplex, often slower and less nearly minimal, to compute a free resolution of a chain complex. See resolutionOfChainComplex for an example.
