Great!!  I created a release branch for 1.1 and updated the POM in
trunk to 1.2, so there will be no contention with the release.  I also
committed the sources in what I think is the latest version to trunk. 
Pls check out and make any changes you see fit.

I think one could argue for including both kinds of things, similiar
to other places in [math].  Provide users with the choice to select an
algorithm or use a default or "adaptive" selection.  I think the basic
interface setup that Xiaogang has is sound - though I am open to
alternatives - and we could (and should) easily add factory support.
