<Verb>FilteredTensorWithIntegers(R):: FreeResolution, Int --> FilteredChainComplex</Verb><P/>

Inputs a free <M>\mathbb ZG</M>-resolution <M>R</M> for which 
<M>"filteredDimension"</M> lies in <B>NamesOfComponents(R)</B>. 
(Such a resolution can be produced using <B>TwisterTensorProduct()</B>, 
<B>ResolutionNormalSubgroups()</B> or <B>FreeGResolution()</B>.) 
It returns the filtered chain complex obtained by tensoring with the trivial 
module $\mathbb Z$.
