Screen Reader Accessibility

Problem/Motivation

I've been using this module for years but I'm doing more work with low vision and blind users recently and discovered that this module makes it impossible for people with screen readers to open the parent terms to select taxonomy terms.

Proposed resolution

From what I can tell, the problem stems from the way the triggers are designed, they're just divs without any link/content to be read. I would think ideally it would work like tabs where the parent text is a link that triggers the section to open/close and could include the +/- graphic. I know this is a significant change but would help Section 508 compliance as well as be a little more intuitive for sighted users as well to be able to click headers to expand and collapse them.
