Wiki - Wave Store TODO's

[Yuri Z]

Hi
I posted a "Wave Store TODO's" doc on the Wiki -
https://cwiki.apache.org/confluence/display/WAVE/Wave+Store+TODO%27s+By+Soren+Lassen
Some of the TODO's were already implemented and currently I am working on
adding MongoDB based indexing - as was designed in the doc above (more or
less).
It would be great if other people can share ideas about possible
alternative designs or maybe even take part in the implementation.
