       /*  LIB FUNCTIONS

       This file contains only functions necessary for the article features
       The full library code and enhanced versions of the functions present
       here can be found at http://v2studio.com/k/code/lib/


       ARRAY EXTENSIONS

       push(item [,...,item])
           Mimics standard push for IE5, which doesn't implement it.


       find(value [, start])
           searches array for value starting at start (if start is not provided,
           searches from the beginning). returns value index if found, otherwise
           returns -1;


       has(value)
           returns true if value is found in array, otherwise false;


       FUNCTIONAL

       map(list, func)
           traverses list, applying func to list, returning an array of values returned
           by func

           if func is not provided, the array item is returned itself. this is an easy
           way to transform fake arrays (e.g. the arguments object of a function or
           nodeList objects) into real javascript arrays.

           map also provides a safe way for traversing only an array's indexed items,
           ignoring its other properties. (as opposed to how for-in works)

           this is a simplified version of python's map. parameter order is different,
           only a single list (array) is accepted, and the parameters passed to func
           are different:
           func takes the current item, then, optionally, the current index and a
           reference to the list (so that func can modify list)


       filter(list, func)
           returns an array of values in list for which func is true

           if func is not specified the values are evaluated themselves, that is,
           filter will return an array of the values in list which evaluate to true

           this is a similar to python's filter, but parameter order is inverted


       DOM

       getElem(elem)
           returns an element in document. elem can be the id of such element or the
           element itself (in which case the function does nothing, merely returning
           it)

           this function is useful to enable other functions to take either an    element
           directly or an element id as parameter.

           if elem is string and there's no element with such id, it throws an error.
           if elem is an object but not an Element, it's returned anyway


       hasClass(elem, className)
           Checks the class list of element elem or element of id elem for className,
           if found, returns true, otherwise false.

           The tested element can have multiple space-separated classes. className must
           be a single class (i.e. can't be a list).


       getElementsByClass(className [, tagName [, parentNode]])
           Returns elements having class className, optionally being a tag tagName
           (otherwise any tag), optionally being a descendant of parentNode (otherwise
           the whole document is searched)


       DOM EVENTS

       listen(event,elem,func)
           x-browser function to add event listeners

           listens for event on elem with func
           event is string denoting the event name without the on- prefix. e.g. 'click'
           elem is either the element object or the element's id
           func is the function to call when the event is triggered

           in IE, func is wrapped and this wrapper passes in a W3CDOM_Event (a faux
           simplified Event object)


       mlisten(event, elem_list, func)
           same as listen but takes an element list (a NodeList, Array, etc) instead of
           an element.


       W3CDOM_Event(currentTarget)
           is a faux Event constructor. it should be passed in IE when a function
           expects a real Event object. For now it only implements the currentTarget
           property and the preventDefault method.

           The currentTarget value must be passed as a paremeter at the moment    of
           construction.


       MISC CLEANING-AFTER-MICROSOFT STUFF

       isUndefined(v)
           returns true if [v] is not defined, false otherwise

           IE 5.0 does not support the undefined keyword, so we cannot do a direct
           comparison such as v===undefined.
