+ @brief <b> PWMapDTOConverter implementation</b>
+
+ The PWMapDTOConverter is used to convert a PWMapDTO
+ to the corresponding piecewise SBG map representation.
+ Currently, it can convert to SBG::LIB::PWMap<UnordSet> (BasePWMap) and
+ SBG::LIB::PWMap<OrdSet> (CanonPWMap), but more conversions can be added.
