Usage: Restricts a subset of network elements included in a list of EIDs, or optionally restricts
those elements NOT in the list of EIDs if FilterSubset_Restrict is false. If FilterSubset_Restrict is false
then in the special case that a source has NO EIDs in the list then no elements are restricted
rather than restricting all elements.
Parameters: (name:defaultvalue; type:domain; description)
-FilterSubset_Restrict:true; Boolean; indicated if listed EIDs should be restricted (FilterSubset_Restrict=true),
or those not in the EID list should be restricted (FilterSubset_Restrict=false)
-FilterSubset_EIDs_<Source>:<null>; integer[]; subset of EIDs for a given source name to filter
(replace <source> with a specific network source name such as streets without angle
brackets to filter a specified subset of element ids for that source. Multiple parameter
EID subset list parameters can be added to filter a subset of multiple network sources.";
