             * Our basic approach here for event handlers is that we listen for a down event (mousedown or touchstart).
             * Once we have a down event, we need to work out whether we have a click, a drag, or a
             * hold.  A click would sort the grid (if sortable).  A drag would be used by moveable, so
             * we ignore it.  A hold would open the menu.
             *
             * So, on down event, we put in place handlers for move and up events, and a timer.  If the
             * timer expires before we see a move or up, then we have a long press and hence a column menu open.
             * If the up happens before the timer, then we have a click, and we sort if the column is sortable.
             * If a move happens before the timer, then we are doing column move, so we do nothing, the moveable feature
             * will handle it.
             *
             * To deal with touch enabled devices that also have mice, we only create our handlers when
             * we get the down event, and we create the corresponding handlers - if we're touchstart then
             * we get touchmove and touchend, if we're mousedown then we get mousemove and mouseup.
             *
             * We also suppress the click action whilst this is happening - otherwise after the mouseup there
             * will be a click event and that can cause the column menu to close
             *

   * @summary A group of directives that provide a one time bind to a dom element.
   * @description A group of directives that provide a one time bind to a dom element.
   * As one time bindings are not supported in Angular 1.2.* this directive provdes this capability.
   * This is done to reduce the number of watchers on the dom.
   * <br/>
   * <h2>Short Example ({@link ui.grid.directive:uiGridOneBindSrc ui-grid-one-bind-src})</h2>
   * <pre>
        <div ng-init="imageName = 'myImageDir.jpg'">
          <img ui-grid-one-bind-src="imageName"></img>
        </div>
     </pre>
   * Will become:
   * <pre>
       <div ng-init="imageName = 'myImageDir.jpg'">
         <img ui-grid-one-bind-src="imageName" src="myImageDir.jpg"></img>
       </div>
     </pre>
     </br>
     <h2>Short Example ({@link ui.grid.directive:uiGridOneBindText ui-grid-one-bind-text})</h2>
   * <pre>
        <div ng-init="text='Add this text'" ui-grid-one-bind-text="text"></div>
     </pre>
   * Will become:
   * <pre>
   <div ng-init="text='Add this text'" ui-grid-one-bind-text="text">Add this text</div>
     </pre>
     </br>
   * <b>Note:</b> This behavior is slightly different for the {@link ui.grid.directive:uiGridOneBindIdGrid uiGridOneBindIdGrid}
   * and {@link ui.grid.directive:uiGridOneBindAriaLabelledbyGrid uiGridOneBindAriaLabelledbyGrid} directives.

       *
       * Most commonly the data is an array of objects, where each object has a number of attributes.
       * Each attribute automatically becomes a column in your grid.  This array could, for example, be sourced from
       * an angularJS $resource query request.  The array can also contain complex objects, refer the binding tutorial
       * for examples of that.
       *
       * The most flexible usage is to set your data on $scope:
       *
       * `$scope.data = data;`
       *
       * And then direct the grid to resolve whatever is in $scope.data:

       * This is the most flexible approach as it allows you to replace $scope.data whenever you feel like it without

       * Alternatively you can directly set the data array:
       *

     *  @name updateColumnWidths
     *  @propertyOf  ui.grid.class:GridRenderContainer
     *  @description Determine the appropriate column width of each column across all render containers.
     *
     *  Column width is easy when each column has a specified width.  When columns are variable width (i.e.
     *  have an * or % of the viewport) then we try to calculate so that things fit in.  The problem is that
     *  we have multiple render containers, and we don't want one render container to just take the whole viewport
     *  when it doesn't need to - we want things to balance out across the render containers.
     *
     *  To do this, we use this method to calculate all the renderContainers, recognising that in a given render
     *  cycle it'll get called once per render container, so it needs to return the same values each time.
     *
     *  The constraints on this method are therefore:
     *  - must return the same value when called multiple times, to do this it needs to rely on properties of the
     *    columns, but not properties that change when this is called (so it shouldn't rely on drawnWidth)
     *
     *  The general logic of this method is:
     *  - calculate our total available width
     *  - look at all the columns across all render containers, and work out which have widths and which have
     *    constraints such as % or * or something else
     *  - for those with *, count the total number of * we see and add it onto a running total, add this column to an * array
     *  - for those with a %, allocate the % as a percentage of the viewport, having consideration of min and max
     *  - for those with manual width (in pixels) we set the drawnWidth to the specified width
     *  - we end up with an asterisks array still to process
     *  - we look at our remaining width.  If it's greater than zero, we divide it up among the asterisk columns, then process
     *    them for min and max width constraints
     *  - if it's zero or less, we set the asterisk columns to their minimum widths
     *  - we use parseInt quite a bit, as we try to make all our column widths integers
