added a tdot function (thanks Iain)
manual merging
James and Nicolos massive Yak shaving session
Added first draft of acclaim mocap functionality.
Fixed two bugs in to_xyz, checked on a test version of MATLAB code.
Added CMU 35 motion capture data.
cmu_mocap() example mostly working except some fiddling with axes for visualization. Also changes to naming of scaling and offset parameters in GP.py and deal with the case where the scale parameter is zero.
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
weaved coregionalise. much performance gained
reimplemented caching in prod_orthogonal...
removed uncollapsed sparse GP. superceeded by the forthcoming svigp package
more stabilisation of sparse GP
Merge branch 'devel' into mrd
