## clientVars
Called from: src/node/handler/PadMessageHandler.js
Things in context:
1. clientVars - the basic `clientVars` built by the core
2. pad - the pad this session is about
This hook will be called once a client connects and the `clientVars` are being sent. Plugins can use this hook to give the client a initial configuriation, like the tracking-id of an external analytics-tool that is used on the client-side. You can also overwrite values from the original `clientVars`.
Example:
```
exports.clientVars = function(hook, context, callback)
{
// tell the client which year we are in
return callback({ "currentYear": new Date().getFullYear() });
};
```
This can be accessed on the client-side using `clientVars.currentYear`.
