Fix what is I think an off-by-one in query and sequence searching.

When taking the mean of the N minimum distances, only consider those
distances which are closer than the infinite/uninitialized distance.

(This renders us potentially vulnerable to an internal consistency
horror where we end up trying to divide by zero.  This is unlikely to be
picked up by unit tests, but might well be by random tests if this is in
fact a problem.)

//general.  Find a way to bind this later (at install time?  Or maybe
//just require that the installer edit the resulting wsdl file?)
