complete(ChainComplex) -- complete the internal parts

Synopsis

Description

complete C -- fills in the modules of a chain complex obtained as a resolution with information from the engine.

For the sake of efficiency, when a chain complex arises as a resolution of a module, the free modules are not filled in until they are needed. This routine can be used to fill them all in, and is called internally when a chain complex is printed. Normally users will not need this function, unless they use # to obtain the modules of the chain complex, or use keys to see which spots are occupied by modules.
