// v1.634
// UNRELEASED last updated 21 May 2010
// alphabginstance to lowercase
// working on horzscroll, brandscroll & marquee replacement.
// added jcID - a uniform & persistant ID for all jc$ elements.
// horzscroll basic up and running
// fixed ie8 bug for horzscroll. Unfortunately now does not self-clean
// refined isnull & isfunc
// realise need to adopt (function($){/*exec*/})(jQuery); approach
// added jc$.timer - time logging for the lazy peeps
// added is_array
// added count();
// added console.error non-fail support for lacking browsers
// added check for global_debug var, if true, some alerts will display
// added console check alert if (global_debug)
// fixed isnull to actually specify T
// added ajaxForm
// added default value for global_debug
// swapped 1:0 for isfunc so it actually works.
// console.log does $('body').append
// added sip
// added extra interface to horzscroll
// added swapKeys, string method extender to do easy find replace.
// fixed 'float' error on brandscroll
// added jc$.randNum
// fixed object cloning in centerscreen
// fixed some incorrect practices here and there.
// added dragMe - lighter version of the jQuery ui drag.
// added getOuterWidth
// added rewind to horzscroll & refactored '_' to 'self'.

// v1.633
// released 26 Mar 2010
// updated centerscreen to include 'show' option. default : 1
// added bswap
// added findpr
// updated screenfill to include 'onresizeshow' & 'show' option. default : 0, 1
// updated screenfill to modern variable name conventions (mvnc)
// updated screenfill to include forced w & h declarations
// updated centerscreen to mvnc.
// updated screenfill to store ratio as element attribute
// updated screenfill to operate based on parent element
// added syntheticHistory. Even works in safari as long as hash is not a real id.
// updated alphabg to auto window.resize
// added setOpac. Allows easy opacity setting via class name eg: class="something anything setOpac-25"
// 	that will set the element to 25% opacity.
// 	call it $.setOpac.init();
// added stylesheet_swap. allows easy cross-browser changing of stylesheets.
//	methods: init, enable, disable, change.
// further updated centerscreen to mvnc - fixed error.
// renamed _grabber on alphabg
// deprecated jcmarquee !!!!!!! - a new function will replace this and brandscroll
// brandscroll updated to use a central jc$ object
// jc$ object beginnings, this will be further refined.
// added in callback to stylesheet_swap and apply style on startup

// v1.632
// released 17 Feb 2010
// Added auto window.resize events to centerscreen & screenfill

// v1.631
// released 8 Feb 2010
// updated centerscreen
//   added auto positioning to element
// this should be checked across all functions
// some rollfade updates got over-written. These have now been fixed.

// v1.63
// released 27 Jan 2010
// added jcmarquee
//  this is an adaptation of brandscroll
//  these two functions badly need to be deprecated and
//  rewritten as a single light function
//  that is highly customisable.
// modified brandscroll_settings identifier.
// 	now : var i = 'bs_'+Math.floor(Math.random()*10102030123);

// v1.62
// released 19 Jan 2010
// changelog:
// fixed rollfade checkclass

// adding date to new versions

// v1.61
// changelog
