SMM11 — "Influence" of measure relationship

Though, for MeasureRelationship in SMM, the "real" influence of one measure to other measure(s) is implied by the type of measure, its functors, operations, accumulators, etc., still it is, for business analyst understanding and maintenance sake very useful to add the influence type explicitly (the analyst may even define it before the actual functor or operation is specified). This will also be helpful in diagrammatic understanding in one glance of how measurements are influencing each other.

Resolution (as agreed with Larry Hines):

Add optional property "Influence" to MeasureRelationship. This is property with enumeration type "Influence", having 2 enum values: "positive", "negative".
In addition: a constraint, specifying that this property is not allowed for "EquivalentMeasureRelationship".
