A container for describing a network attribute evaluator whose values are derived from a constant value.
A NetworkConstantEvaluator is an evaluator that assigns a constant value, such as 0, to a network attribute of all network elements. This could be used to initialize a given attribute, such as the number of people dropped off at bus stops. Another example is setting travel time across junction elements to zero.
