/* Accordion
 * 
 * Styling AccordionContainer basically means styling the accordion pane (dijitAccordionInnerContainer)
 * and the title inside of it (dijitAccordionTitle).   There are 4 basic states to style:
 * 
 * 1. closed pane (and default styling): 
 * 		.dijitAccordionInnerContainer - container for each accordion child
 * 		.dijitAccordionTitle - title for each accordion child
 *
 * 2. active closed pane (ie, mouse down on a title bar)
 * 		.dijitAccordionInnerContainerActive - for background-color, border
 * 		.dijitAccordionInnerContainerActive dijitAccordionTitle - for text color
 * 
 * 3. open pane (expanded child)
 *		.dijitAccordionChildWrapper - wraps around the child widget (typically ContentPane)
 *			setting a margin so that there's blue trim all the way around the child
 *
 * 		These rules need to override the closed pane active:
 *
 * 		.dijitAccordionInnerContainerSelected - for background-color, border
 * 		.dijitAccordionInnerContainerSelected .dijitAccordionTitle - for text color
 * 
 * 4. hovered pane, open or closed
 * 		The selectors below affect hovering over both a closed pane (ie, hovering a title bar),
 * 		and hovering over an open pane.   Also, treat mouse down on an open pane as a hover:
 *
 * 		.dijitAccordionInnerContainerHover, .dijitAccordionInnerContainerSelectedActive - for background-color, border
 * 		.dijitAccordionInnerContainerHover .dijitAccordionTitle - for text color
