Spherical grid direct product.
Tiles one grid using the rotations of the other. Grids should be supplied using Euler angles in three columns [alphas betas gammas] in radians.
angles1 - angles of the first grid, as [alpha beta gamma], rad weights1 - weights of the first grid angles2 - angles of the second grid, as [alpha beta gamma], rad weights1 - weights of the second grid
angles - angles of the product grid, as [alpha beta gamma], rad weights - weights of the product grid
Grid files are located in kernel/grids directory.
The function is provided for research purposes, but it is generally not a good idea to obtain spherical grids by taking direct products of smaller ones. Use repulsion.m to obtain very good grids of any size.
