hpricot-pure - simply Hpricot, just made "pure".

PREMISE: THIS IS JUST AN EXPERIMENT

Ok I was just bored, but as an unexpected result of my boredom, hpricot-pure turned out to be actually functioning after a couple of hours of laid-back hacking so I thought "why not releasing the source code?".

hpricot-pure is a version of Hpricot that doesn't rely on a native extension, instead it is written entirely in pure Ruby. It is currently based on Hpricot 0.6.164 and I have no plans to support later versions of Hpricot, but I might reconsider this after pushing out the new features of Hpricot into ironruby-hpricot.

Ok so now what is the point of hpricot-pure? Well, as I have said I was bored, there is really nothing much to say. But I can't exclude that someone may find it useful :)

NOTE: there is a known bug! Actually, when the source string/io does not fit in the buffer, hpricot-pure skips a character when reading the next chunk of data. I'm still not sure if this is a bug introduced by the ragel-generated code or if I'm missing something, but it is indeed worth of an in-depth examination.
