Davis King c1443d4d1e Added some tests to make sure that both the ekm and lisf objects 
measure projection error the same way.

Davis King 3e9a0d426f Fixed incorrect requirements in the kcentroid constructor. They were a 
little too weak.

Davis King 1650d8e95c Simplified the code for reduced() and reduced2() by making them use the 
kernel_matrix() and fill_lisf() funcions instead of the many for loops
they previously had.  In particular, using fill_lisf() makes the reducers
generally a lot faster and a little more accurate.

so.

Davis King 260c893c7f Added these new functions: remove_long_edges(), remove_percent_longest_edges(),

the graph creation functions to make them a little more versatile.  Now
you can use infinite distances to indicate that certain nodes are not
connected at all.

Davis King 0c2cb034a3 Added all missing asserts for the manifold_regularization code. Also 
removed unnecessary requirement that distances be non-negative for the
graph creation tools.  All that really matters is that edge weights
are non-negative.  A user can use that distance float for whatever they
want as long as the above remains true.
