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

@param name of the variable which holds the Line
@param index of the Line within the variable
@return a new line with all associated information
Returns a Line given a variable name and the geometric index . If the Line is not found it will return null . If the Line is a part of the Multi - Line it will return the head ( the first Line in the series which constitutes the Multi - Line ) .
