  IPPU methods:
     init([innerHTML]) -- takes innerHTML as optional argument
     show() -- shows the popup
     hide() -- hides popup
     cancel() -- hides and calls cancel callback

  Content setters:
     setContent(innerHTML) -- set innerHTML
     setContentElement(element) -- adds element as a child of the popup

   Accessors:
     getElement() -- returns popup DIV element
     visible() -- returns whether the popup is visible or not

   Titlebar:
     setTitlebar(show) -- true: show titlebar / false: no titlebar
     setTitle(title) -- sets the titlebar text
     getTitlebarElement() -- returns the titlebar element
     setTitlebarClass(className) -- set the class of the titlebar

   Styling:
     setOverflow(overflow) -- sets ele.style.overflow to overflow
     addClass(className) -- adds class to popup
     removeClass(className) -- removes class to popup

   Browser Hacks:
     setAutoHideSelects(autohide) -- when the popup is shown should it find all the selects
                                on the page and hide them (and show them again) (for IE)

   Positioning/Sizing:
     setLocation(left, top) -- set popup location: will be pixels if units not specified
     setLeft(left) -- set left location
     setTop(top)   -- set top location
     setDimensions(width, height) -- set popup dimensions: will be pixels if units not specified
     setAutoCenter(x, y) -- what dimensions to auto-center
     center() -- centers popup on screen
     centerX() -- centers popup horizontally
     centerY() -- centers popup vertically
     setFixedPosition(fixed) -- should the popup stay fixed on the page when it scrolls?
     centerOnWidget(widget) -- center popup on this widget
     setAutoCenterCallback(callback) -- calls callback with this IPPU instance as a parameter
                                        for auto-centering. Some common built-in class methods
                                        you can use as callbacks are:
                                        IPPU.center
                                        IPPU.centerX
                                        IPPU.centerY

     moveForward(amount) -- increases the zIndex by one or amount if specified
     moveBackward(amount) -- decreases the zIndex by one or amount if specified

   Modality:
     setClickToClose(clickToClose) -- if clickToClose is true, clicking outside of the popup
                                      will close it
     setModal(modality) -- If modality is true, then popup will capture all mouse events
                     and optionally gray out the rest of the page. (overrides clickToClose)
     setOverlayVisible(visible) -- If visible is true, when this popup is on the page it
                                   will gray out the rest of the page if this is modal

   Callbacks:
     setCancelledCallback(callback) -- call this when the dialog is closed through clicking
                                       outside, titlebar close button, etc...
     setHiddenCallback(callback) -- called when the dialog is closed in any fashion

   Fading:
     setFadeIn(fadeIn) -- set whether or not to automatically fade the ippu in
     setFadeOut(fadeOut) -- set whether or not to automatically fade the ippu out
     setFadeSpeed(secs) -- sets fade speed

  Class Methods:
   Handy callbacks:
     IPPU.center
     IPPU.centerX
     IPPU.centerY
   Browser testing:
     IPPU.isIE() -- is the browser internet exploder?
     IPPU.ieSafari() -- is this safari?

     content -- DIV containing user's specified content
     clickToClose -- boolean; clicking outside popup will close it
     clickHandlerSetup -- boolean; have we set up the click handlers?
     docOverlay -- DIV that overlays the document for capturing clicks
     modal -- boolean; capture all events and prevent user from doing anything
                       until dialog is dismissed
     visibleOverlay -- boolean; make overlay slightly opaque
     clickHandlerFunc -- function; function to handle document clicks
     resizeHandlerFunc -- function; function to handle document resizing
     autoCenterCallback -- function; what callback to call for auto-centering
     cancelledCallback -- function; called when dialog is cancelled
     setAutoHideSelects -- boolean; autohide all SELECT elements on the page when popup is visible
     hiddenSelects -- array; SELECT elements that have been hidden
     hiddenCallback -- funciton; called when dialog is hidden
     fadeIn, fadeOut, fadeSpeed -- fading settings
     fadeMode -- current fading mode (in, out) if there is fading going on

    Methods:
     updateTitlebar() -- create titlebar if it doesn't exist,
                         hide it if titlebar == false,
                         update titlebar text
     updateContent() -- makes sure all currently specified properties are applied
     setupClickCapture() -- if modal, create document-sized div overlay to capture click events
                            otherwise install document onclick handler
     removeClickHandlers() -- remove overlay, event handlers
     clickHandler() -- event handler for clicks
     updateOverlay() -- if we have an overlay, make sure it's where it should be and (in)visible
                        if it should be
     autoCenter() -- centers popup on screen according to autoCenterX and autoCenterY
     hideSelects() -- hide all select element on page
     showSelects() -- show all selects
     _hide () -- actually hides everything, called by hide(), which does fading if necessary

  Class: InputCompleteData

  About: An InputComplete object needs a data source to auto-complete
          from.  This is that model.  You can create one from an
          array, or create a lazy version that gets its data over the
          network, on demand.  You will probably not use this class'
          methods directly, as they're called by the InputComplete
          object.

          The closer a word is to the beginning of the array, the more
          likely it will be recommended as the word the user is typing.

          If you pass the string "ignorecase" as the second argument in
          the constructor, then the case of both the user's input and
          the data in the array will be ignored when looking for a match.

  Constructor:

    var model = new InputCompleteData ([ "foo", "bar", "alpha" ]);
