// labels.js 1.0
// lives at : www.thestandardhack.com/components/labels.html (soon my friend)
// born by  : aaron boodman aaron@youngpup.net www.youngpup.net
// reporposed for SunRocket by NavigationArts: navarts.com
//==============================================================================
// this file uses the html label element to create one of those chill default 
// label things for form elements that flicks on and off when you focus and 
// blur the element.
//
// some cool features: 
//  - it uses event listening, so it doesn"t interfere with anything else.
//  - it"s easy to use: just drop this file in the head of your document.
//  - it degrades (users see traditional HTML labels)
//  - it cleans itself up before unload so that labels are never accidentally
//    submitted through forms.
//
// everything would be alot simpler if IE would just let you change the type
// of an input element (as mozilla does and the spec requires)
//==============================================================================

//==============================================================================
// Setup
//==============================================================================
// - turn display of labels off
// - initialize all labels
// - arrange for uninit to be called before any form submissions
//==============================================================================
