Adding Angular API to non-Spark interpreters

[Randy Gelhausen <rg...@gmail.com>]

I often need to visualize data in other ways than supported by the out of
the box charts. I can do this with Angular notes and custom JavaScript, but
Spark is the only interpreter with capability to set Angular variables.

Could it be possible to automatically expose all interpreter results as
Angular variables using the paragraph ID as the variable name?

This would greatly improve the custom viz capabilities for Zeppelin without
requiring developers of each interpreter to integrate with Zeppelin's
Angular API.
