Remarks

DefaultTargetDestinationCount specifies the number of destinations to find for the NAODCostMatrixSolver.  For example, solving for 10 destinations will return the cost-distance to the 10 closest destinations from each origin.

DefaultTargetDestinationCount is considered default because it can be overridden on a feature-by-feature basis by the presence of a non-null value in the TargetDestinationCount field of an individual feature.

DefaultTargetDestinationCount, if not NULL, can be cast as an integer.  It is returned as an object/variant in order to allow a NULL value to be used to specify an unlimited default destination count.  A DefaultTargetDestinationCount of NULL indicates that a path will be found, if possible, between every origin and every destination.

If a specific origin feature has a non-null value in the TargetDestinationCount field of its NAClass, this value will override the DefaultTargetDestinationCount for that origin. 

If an attempt is made to set the DefaultTargetDestinationCount to a non-integer value, it will be rounded to the nearest integer.
