dc33aa1b8c used scipy.weave to improve the speed of rbf grads 
for large number of input dimensions with ARD, wqe have approx tenfold
speedup.

52ba8e4ba3 remo0ved slices from models 
slices are now handles by special indexing kern parts, such as
coregionalisation, independent_outputs. The old slicing functionality
has been removed simply to clean up the code a little.

Now that input_slices still exist (and will continue to be useful) in
kern.py. They do need a little work though, for the psi-statistics
