<P/>Inputs a simplicial, pure cubical, cubical or pure permutahedral complex 
<M>K</M>
and returns the corresponding regular CW-complex.

Inputs a list <M>L=Y!.boundaries</M> of boundary incidences of a regular CW-complex <M>Y</M> and returns <M>Y</M>.  

Inputs a list <M>L=Y!.boundaries</M> of boundary incidences of a regular CW-complex <M>Y</M> together with a list <M>M=Y!.orientation</M> of incidence numbers and returns a regular CW-complex <M>Y</M>. The availability of precomputed 
incidence numbers  saves recalculating them.
