// Animate (11-January-2010)
// by Vic Phillips http://www.vicsjavascripts.org.uk
// To progressively change the Left, Top, Width, Height or Opacity of an element over a specified period of time.
// With the ability to scale the effect time on specified minimum/maximum values
// and with three types of progression 'sin' and 'cos' and liner.
// **** Application Notes
// **** The HTML Code
//
// when moving an element the inline or class rule style position of the element should be assigned as
// 'position:relative;' or 'position:absolute;'
//
// The element would normally be assigned a unique ID name.
//
// **** Initialising the Script.
//
// The script is initialised by assigning an instance of the script to a variable.
// e.g A = new zxcAnimate('left','id1')
// where:
// A = a global variable (variable)
// parameter 0 = the mode(see Note 1). (string)
// parameter 1 = the unique ID name or element object. (string or element object)
// parameter 1 = the initial value. (digits, default = 0)
// **** Executing the Effect
//
// The effect is executed by an event call to function 'A.animate(10,800 ,5000,[10,800]);'
// where:
// A = the global referencing the script instance. (variable)
// parameter 0 = the start value. (digits, for opacity minimum 0, maximum 100)
// parameter 1 = the finish value. (digits, for opacity minimum 0, maximum 100)
// parameter 2 = period of time between the start and finish of the effect in milliseconds. (digits or defaults to previous or 0(on first call) milliSeconds)
// parameter 3 = (optional) to scale the effect time on a specified minimum/maximum. (array, see Note 3)
// field 0 the minimum value. (digits)
// field 1 the maximum value. (digits)
// parameter 3 = (optional) the type of progression, 'sin', 'cos' or 'liner'. (string, default = 'liner')
// 'sin' progression starts fast and ends slow.
// 'cos' progression starts slow and ends fast.
//
// Note 1: Examples modes: 'left', 'top', 'width', 'height', 'opacity.
// Note 2: The default units(excepting opacity) are 'px'.
// For hyphenated modes, the first character after the hyphen must be upper case, all others lower case.
// Note 3: The scale is of particular use when re-calling the effect
// in mid progression to retain an constant rate of progression.
// Note 4: The current effect value is recorded in A.data[0].
// Note 5: A function may be called on completion of the effect by assigning the function
// to the animator intance property .Complete.
// e.g. [instance].Complete=function(){ alert(this.data[0]); };
//
// **** Functional Code(1.52K) - NO NEED to Change
