Drupal gaps

The goal of this project is to fill in many of those tiny gaps in Drupal API that didn't make it to the official core release. Most of this code could and probably at some point will be part of Drupal core but because many developers value their time, they can't afford waiting for community consensus on every tiny implementation detail. On the other hand it's sometimes ridiculous to create entire project just to add missing field validator. So this is the place for all these tiny bits of code.

It's not another Chaos Tools. I'm only trying to fill in the missing bits that I stumble upon while developing Drupal modules.
