* 
* collapsor opens and closes sublevel elements, like a collapsable menu
*
* We need to select the clickable elements that trigger the opening action of the sublevels: $('#menu ul li a').collapsor();
* The sublevel element must be in the same level than the triggers
*
* Sample Configuration:
* $('ul a').collapsor();
* 
* Config Options:
* openClass: Class added to the element when is open // Default: 'open'
* sublevelElement: Element that must open or close // Default: 'ul'
* closeOthers: Close other elements when opening // Default: false
* speed: Speed for the opening animation // Default: 500
* easing: Easing for the opening animation. Other than 'swing' or 'linear' must be provided by plugin // Default: 'swing'
* 
* We can override the defaults with:
* $.fn.collapsor.defaults.speed = 1000;
* 
* @param  settings  An object with configuration options
