Testing separate_fields_by_distance is not actually testing anything

[dragly]

The following lines compares pos_true to pos_true, which will always be true. It should test against peaks, but changing pos_true to peaks fails the test currently, so there is something else that needs to be done:

spatial-maps/spatial_maps/tests/test_gridcells.py

Lines 48 to 52 in 18c4281

	peaks, radius = separate_fields_from_distance(rate_map)
	bump_centers = np.array([xbins[peaks[:,0]], ybins[peaks[:,1]]])
	# The position of a 2D bin is defined to be its center
	for p in pos_true:
	assert np.isclose(p, pos_true).prod(axis=1).any()

good catch!! should be peaks, probably just some shape difference in ordering of the peaks or similar. I'll fix soon
