Add Data Reviewer advanced check for checking M:N relationship classes

Idea created by jborovanskyarcdata-cz-esridist Employee on Mar 24, 2015
    With Esri support we verified that there is no way how to check following checks when need to compare feature class and M:N relationship class.
    Use Case:
    Control definition for point feature class (FC):
    checkquery: whereclause="TYPE in (1,2,5)"
    check expression: "RELATIONSHIP_CLASS_NAME" min="1" max="1" not="true">
    check err message: "This type of point must have exactly one related feature in given relationship class"

    This example says - find all point features that do not have exactly 1 record within the M:N relationship class.
