Rainbow colours in Emacs

I use two different emacs packages called rainbow-identifiers and rainbow-delimiters to colorize two different things in Emacs to make code more readable.

identifiers gives different identifiers like variables, functions or operators different colors so you can easier to distinguish between them and see where something is used.

delimiters on the other hands makes sure that deliminers like (), [], {} have different colors. This can be very useful in a number of sitations, especially in lips where you often see a lot of them. And it makes it possible with a glance to identify where an expression starts and ends.
