Merge Interval Showplan Operator

The Merge Interval operator merges multiple (potentially overlapping) intervals to produce minimal, nonoverlapping intervals that are then used to seek index entries. This operator typically appears above one or more Compute Scalar operators over Constant Scan operators, which construct the intervals (represented as columns in a row) that this operator merges.

Merge Interval is a logical and physical operator.
