This function does a Cloud-In-Cell projection of a 3d unstructured dataset. First argument is a Nx3 array of coordinates.
Second argument is an optinal mass. Ngrid is the size output grid and Lbox is the physical size of the grid.
if output is not None, it must be a numpy array with dimension NgridxNgridxNgrid. The result will be accumulated in that array.
