23 History:
24  Base implementation copied from NX. The code was copied as this class was available in
25  latest NX libraries which are currently not supported in Tc.
26  The implementation in NX uses code from Boost library, hence a reference to Boost license in included.
27 
28 Changes were made to NX code to conform it to Tc. These changes include :
29 - namespace change
