2021-03-15	Implement simplified cone sampling algorithm.	Arun Isaac
	* contrib/cone-vector.py: Don't import tan. (random_vector_on_spherical_cap): Implement simplified algorithm that directly samples the surface of the sphere instead of sampling a disk and projecting it onto the surface.
2021-03-15	Vectorize functions.	Arun Isaac
	* contrib/cone-vector.py: Import where. (planar_angle2solid_angle_fraction, solid_angle_fraction2planar_angle): Vectorize functions.
2021-03-15	Fix solid_angle_fraction2planar_angle for solid_angle_fraction > 1/2.	Arun Isaac
	* contrib/cone-vector.py (solid_angle_fraction2planar_angle): Fix for solid_angle_fraction > 1/2.
2021-03-10	Do not concatenate numpy arrays.	Arun Isaac
	* contrib/cone-vector.py: Import empty. Don't import concatenate. (random_vector_on_spherical_cap): Build random vector without concatenation.
2021-03-10	Remove surface area computation.	Arun Isaac
	Now that we are computing solid angle fractions, there is no need to compute the total surface area of the sphere. * contrib/cone-vector.py (surface_area_of_ball): Delete function. (solid_angle_fraction2planar_angle): Remove surface area computation.
2021-03-10	Add Python implementation of cone sampling.	Arun Isaac
	* contrib/cone-vector.py: New file.
