Minor doc improvement in StructuredLabels constructor
Fixed initialization of DynArray in Parameter/ParameterMap to get memory footprint small:
DynArray will be instanciated 5 times for each SGObject (via Parameter/ParameterMap)
which introduced a memory overhead of 5kb per instance.  With this commit, the overhead
should be reduced to 160 bytes.
