Arguments:
	obj - the object to inspect.

Example:
	>var myString = 'hello';
	>$type(myString); //returns "string"

Returns:
	'element' - if obj is a DOM element node
	'textnode' - if obj is a DOM text node
	'whitespace' - if obj is a DOM whitespace node
	'arguments' - if obj is an arguments object
	'object' - if obj is an object
	'string' - if obj is a string
	'number' - if obj is a number
	'boolean' - if obj is a boolean
	'function' - if obj is a function
	'regexp' - if obj is a regular expression
	'class' - if obj is a Class. (created with new Class, or the extend of another class).
	'collection' - if obj is a native htmlelements collection, such as childNodes, getElementsByTagName .. etc.
	false - (boolean) if the object is not defined or none of the above.
*/
/*
Function: $time
	Returns the current timestamp

Returns:
	a timestamp integer.
*/
/*
Function: $random
	Returns a random integer number between the two passed in values.

Arguments:

	max - integer, the maximum value (inclusive).

Returns:
	a random integer between min and max.
*/
/*
Function: $pick
	Returns the first object if defined, otherwise returns the second.

Arguments:
	obj - object to test
	picked - the default to return

Example:
	(start code)
		function say(msg){
			alert($pick(msg, 'no meessage supplied'));
		}
	(end)
*/
/*
Function: $chk
	Returns true if the passed in value/object exists or is 0, otherwise returns false.
	Useful to accept zeroes.

Arguments:
	obj - object to inspect
*/
/*
Function: $clear
	clears a timeout or an Interval.

Returns:
	null

Arguments:
	timer - the setInterval or setTimeout to clear.

Example:
	>var myTimer = myFunction.delay(5000); //wait 5 seconds and execute my function.
