* ########################################################
*
* Change History:
*
* March 3, 2010 - v1.1.3 ---- Added code to ensure that all vtabs-content-panel elements are at least as tall as the tabColumn element.
* This is to address issue #1, http://code.google.com/p/jquery-vert-tabs/issues/detail?id=1
*
* February 8, 2010 - v1.1.2 - More bug fixes...sigh. Plugin now keeps track of options for each tab set via the
* allTabOptions object.
*
* February 6, 2010 - v1.1.1 - Bug fix dealing with varying length tabs that go beyond the default CSS width of 150px.
*
* February 5, 2010 - v1.1 --- Added set selected tab function.
* (e.g. $("#elm").jVertTabs('selected',2); // select 3rd tab, 0-based.)
*
* February 3, 2010 - v1.0 --- Initial release.
*
*
* ------------------------------------------------------
*
* default options
*
* selected: Index of the tab to open on initialization. 0-based, first tab is 0, second tab is 1, etc..
*
* select: A callback function that is called when a tab is clicked. The 'index' value will be the index of
* the tab that was clicked. 0-based, first tab is 0, second tab is 1, etc..
*
* spinner: Text to show during ajax request. Pass in empty string to deactivate that behavior.
*
* equalHeights: If set to true the content panels will all have the same height. The min-heigh value
* for each panel will be set to that of the tallest panel in the group. By default this
* feature is turned off, or "false". Set to "true" to turn on.
