Matrix == Matrix currently checks that the sources and targets are the same module, which ignores the bases of the source or target, e.g. in the case when they are image modules.
Here are tests whi…

The function `prependZeroMap` unintentionally changes the sign of the differential,
because the operation `C[-1]` intentionally does so. Now that comparison of chain
complexes has been repaired, a …

When tensoring chain complexes, tensor products of two `0 x n` matrices don't work correctly:
```
sage: C = ChainComplex({0: matrix(ZZ, 0, 1)}, degree=-1)
sage: ascii_art(C)
0

We should have an easy way of shifting a chain complex up or down in degree.
