#Rainbow Parentheses Improved

This is a fork of Rainbow Parentheses Improved by luo chen.

I've applied some minor corrections and modifications to it:

• Operators outside any braces get the last color of the rainbow. Previously, it was being ignored for highlighting.
• Simplified/corrected logic to define highlighting precedence for braces as higher than for operators. So if you got a brace that's also an operator and you got to the situation that it can match both roles, it'll assume the brace role.
• Changed default colors. Seems good to test with the mustang colorscheme.
• Changed default highlighted operators (now most punctuation) and highlighted braces (added < and >).

Angle brackets are a hard case to deal with. To distinguish "less than" from "bracket for open template argument list" it's assumed that "less than" will always be surrounded by spaces, if not, it will be treated as an open template angle bracket. Although, even if < is surrounded by spaces, there's still some case elimination by checking for the template or operator keyword for example.

This fork is optimized for C++ highlighting in dark colorschemes by default.

Put this on your .vimrc:

let g:rainbow_operators = 2 
au FileType c,cpp,objc,objcpp call rainbow#activate()

I recommend VAM or Vundle for plugin management.

Here's a sample of one vim session.

I thank Luo for being supportive and accepting the operator highlighting idea.
