Returns a Point given a variable name and the geometric index. If the Point is not found it will return null. If the Point is a part of the Multi-Point, it will return the head
(the first Point in the series which constitutes the Multi-Point).

@param name of the variable which holds the Point
@param index of the Point within the variable
@return a new Point with all associated information
