removing unused mwclient.js
fixed minor typo and starting to expose variable groups to pymworks
needs testing: type matching for js client, this required hacking part of socket.io.js to allow NaN in json [which is out of spec but python allows this by default], also, need to figure out a good way to edit objects
Merge branch 'master' of github.com:braingram/pymworks
better input type casting and NaN handling for js client
