View the DOM from plugin

[dylan1951]

For some use cases it is necessary for the plugin to see the DOM.

For example, consider a web based game where you have many character profiles and you want to prove the level of a specific character.

Assume that when you click a character from your characters list, it fetch's the character data using the API endpoint api.game.com/character/1234 but it remains on the same page game.com/characters.

The only way for the plugin to know which character ID to notarise would be to either:

1. Pass a parameter to the plugin as suggested in Passing params when run plugin #149
2. Allow the plugin to see which character is currently selected in the DOM (along with its ID).
