ghc core with style

After reading one too many time ghc core's output, i've been itching to have a more interactive output.

ghc-core-html is the result of scratching my itch, and i think it could be useful in general to anyone. It creates a html output similar to what ghc-core does in a terminal, but with also the following benefits:

An example is worth thousand words: Example 1

It's really simple to use, and very similar to the well known ghc-core:

> ghc-core-html Program.Hs > program.html
> $browser program.html

There's lots of other things that can be added, and style and javascript can easily be improved. Pull requests gladly accepted at: github repository
