How to access array elements?

On the down side we seem to have lost a lot of tampers from D7; on the plus side, its pretty easy to create your own. Found a lot of old docs on D7 and some for D8 which don't include creating new Tamper (not Feeds or Feeds Tamper) plugins. Easiest is to look at the existing tamper plugins that come with the Tamper module.

I attached one that i created for selecting array elements.

Thanks for your contribution! In order for this to be added to the module, the following is needed:

• Config schema for the plugin's settings
• A unit test
• A functional test

You say that you've lost a lot of Tamper plugins. Which plugins are you missing? According to #2958013: [META] port remaining feeds tamper plugins → there are only two that aren't completely ported yet from the D7 version of Feeds Tamper.

Added schema, functional, and unit tests. Updated some of the functionality to do what the non integer selectors describe. If the functionality in the original patch is preferred then the non integer selectors should probably be updated to be more accurate.

Rebased patch off dev branch instead of release branch.
