Typing speed test

Ooooooh how fast are ya?! Based on the CSS Tricks poll (June 2014) "How much do you value your keyboard typing skills?". Checks if the most recently hit key matches a string.

You can click reset to start again, or change text to reveal the textarea where you can insert your own passage. No cheating now...
