Computes whether the given connection is a left mover across the junction.

It is assumed, that it is a left-mover if the clockwise angle is lower than the counter-clockwise angle.

Parameters:

[in]	from	The incoming edge (the begin of the connection)
[in]	from	The outgoing edge (the end of the connection)

Returns:: Whether the described connection is a left-mover
