  jQuery Simple Placeholder Plugin v0.1r1

  This plugin is designed to give a placeholder to text edit boxes.  
  This placeholder will change colors when the user focuses/unfocuses 
  the placeholder.  If the user inputs any character, then the placeholder
  disappears and the key press registers as normal.  If the user leaves the
  edit box blank, then the placeholder is restored.  The user inputted text
  will not change colors.

  Options:

  colors : An object containing focus and normal color options.
  		focus : the color that the placeholder changes to on focus
		normal : the standard color of the text.

  placeholder : A string that is used as the placeholder text.	


  Example:

  HTML
  <div id='placeholder'></div>

  JavaScript
  $('#placeholder').placeholder();
