static HeadingVector Britbot.HeadingVector.adjustHeading	(	HeadingVector	hv1,
		HeadingVector	hv2
	)		`[inline, static]`

this static method updates the direction based on the new one if the new direction is not to far from the one given (up to 90 degrees) it simply adds to the previous count vector otherwise, we assume there was a change in course and so we start again

Parameters:

hv1	the main direction, the one we comparing the other to
hv2	the new heading

Returns:: itself if we need to use many operation in the same line
