Document "Code" usage

[vasiliy-t]

Haven't found docs on how to use "Code" tab in webui:

• what's under this tab
• what it is capable of
• possible use cases
• step by step guide on how to write code
• possible drawbacks (e.g. live code is not versioned in git)

I don't get what you expect to see in doc. "Open the page, type some letters, apply the config". What else?

[opomuc]

The page is called "Code", but only configuration or some user-written code can be changed/applied. There is no description on what can be changed through this page, how to use the code you've written, where is it stored, how can you invoke it through HTTP or iproto.

Those are just tip of the iceberg I think
