## <Description>
## Sets the property handling functions for a SCPropertyObject <Arg>po</Arg> to the functions described in the record <Arg>handlers</Arg>. The record <Arg>handlers</Arg> has to contain entries of the following structure: <C>[Property Name]:=[Function name computing and returning the property]</C>. For <C>SCSimplicialComplex</C> for example <Package>simpcomp</Package> defines (among many others): <C>F:=SCFVector</C>. See the file <C>lib/prophandler.gd</C>.
