Syntax highlighting for Zeppelin Notebooks

While using the notebook feature in zeppelin the following syntax highlighting features should be available for ease of use:

• Should support - Python, Scala, Java and JS (Angular Interpreters)
• Syntax highlighting with focus on Richness & Correctness.
• Display of line numbers

In addition

• highlighting should also be fast and not degrade performance/experience
• size of library should be a consideration while integration.
