Scalar Functions
Forces the vertices of a geometry to have X, Y and M components  
The following cases apply:  
* If the input geometry has a Z component but no M component, the Z component will be replaced with the new M value.
* If the input geometry has a M component but no Z component, it will be returned as is.
* If the input geometry has both a Z component and a M component, the Z component will be removed.
* Otherwise, if the input geometry has neither a Z or M component, the new M value will be added to the vertices of the input geometry.
