Represents the ST_Overlaps spatial predicate function that tests if two geometries overlap.

Remarks
The ST_Overlaps function returns true if the two spatial objects have the same dimension, share some but not all points in common, and the intersection has the same dimension as the geometries themselves. According to the DE-9IM model, this means their interiors intersect, but neither geometry is completely within the other. Typically used for polygon-polygon or line-line comparisons. Useful for finding partially overlapping features like overlapping land parcels or service areas. OGC-compliant.
