Find the rotation matrix that aligns one three-dimensional vector with another.

	import numpy as np

	def rotation(v1, v2):
	"""
	Compute a matrix R that rotates v1 to align with v2.
	v1 and v2 must be length-3 1d numpy arrays.
	"""
	# unit vectors
	u = v1 / np.linalg.norm(v1)
	Ru = v2 / np.linalg.norm(v2)
