Validation upon save or on demand

[selimfirat]

We need to implement validation checks upon Save (or when the user decides to do such a check).

We should also decide on

• under what menu to make this operation available
• with what format any warnings/errors should be presented to the user

We should discuss whether or not we use libSBGN (http://www.sbgn.org/LibSBGN) for this purpose on server side (not currently available in JavaScript).

In case we support multiple notation (i.e. PD and AF), we should be careful.

Or maybe until libSBGN is available for validation, maybe we can at least check the symbols of genes on demand using the portals web service (see this).

We might be able to do this suing:

which will be used by libsbgn.js.
