intersectLibrary "intersect"
Find Line Intersection X/Y coordinates.
Simple to use, will find intersection if it exists on the segments
if the line segments do not cross on segment, an 'na' value will be returned
if you plot new items with the output coords, they still plot.
avoid this by setting a na(x) condition before plotting new items
get(l1, l2, ( optional _round) )
line intersection coordinates
Parameters:
l1 : (line) first line
l2 : (line) second line
_round : True to make an INT for plotting
if not used, will not round ( overload loophole)
Returns: with x as int if bool is used
