@"Scale Subset Evaluator:

Usage: Returns the base attribute value times a ScaleSubset_Factor for a subset of
elements of a base attribute (and non-scaled elements simply return a non-scaled
base attribute value for the element).  The base attribute and this evaluator's
attribute should both be a double cost attribute of the same units.  The base
attribute is implied by this evaluator's attribute name. The base attribute name
is the part of this evaluator's attribute name after the first underscore ('_')
character. So, if this attribute is 'ScaleSubset_Minutes', then the base attribute is
'Minutes'. The parameter values indicate the ScaleSubset_Factor and the subset of elements to
be scaled.

Parameters: (name:defaultvalue; type:domain; description)
-ScaleSubset_Factor:1; double:>0; the amount to scale applicable base attribute values
-ScaleSubset_EIDs_<Source>:<null>; integer[]; subset of EIDs for a given source name to scale
(replace <source> with a specific network source name such as streets without angle
brackets to scale a specified subset of element ids for that source.  Multiple parameter
EID subset list parameters can be added to scale a subset of multiple network sources.";
