ILocationSpanContainsChainage Method (Double, Double)

Decides wheather a chainage value is contained inside the location span chainage values or on the edge of the span. Comparison uses the tolerance, i.e., the chainage can be tolerance outside the span and still be contained. Negative values for tolerance are allowed ("shortening" the span)

bool ContainsChainage(
	double chainage,
	double tolerance
)
