Clipperz application ported to GEA

[Giulio Cesare Solaroli]

Hello,

while waiting for my GEA invitation, I have take some time to port the
community.edition of the Clipperz application (written in PHP) to the
GEA SDK.
More details available here:

As noted on the post, there may be some issues when deploying the
application on the online service, but I think this could be a nice
example for people trying to understand better how to use GEA.

Interesting features with regard to GEA development:
- custom registration/login procedure without relying on Google accounts;
- custom session management (even if the cleanup code has still some
issues, mostly due to transaction constraints);
- static content / template;
- ajax calls using JSON content;
- simple data structure with references mapped to BigTable;

If anybody is interested, drop me a line and I will pack it up and
upload somewhere.

Regards,

Giulio Cesare
