abv ab860031bd 0025202: Incorrect value of IsClosed flag in shapes produced by some algorithms 
Method BRep_Tool::IsClosed() extended to analyze closure of wires in addition to shells and solids.
External and Internal edges and vertices are ignored in this check.
Analysis of compounds is disabled.

Update of flag Closed according to actual state is added in most places where new shells are constructed.
