Plugin Request: Rainbow parenthesis

[alecGraves]

rainbow parenthesis - coloring matching parenthesis with different colors.

Description with example screenshot: http://emacs-fu.blogspot.com/2011/05/toward-balanced-and-colorful-delimiters.html

This plugin would be nice for editing lisp code or delimiter-heavy code in general.

See some example plugins implementing rainbow delimiter functionality:

• Vim plugin: home | source (download)
• Emacs plugin: home | source
• Intellij plugin: home | source

I implemented this here. It also colors brackets and braces.

I took inspiration from the VSCode "bracket-pair-colorizer" extension and copied the default colors for light and dark backgrounds.
