### Template Popover

Uses bootstrap popover but lets you supply an angular template to render as the popover body. For example here's a simple template for the popover body:

You can then supply this template as an argument to hawtioTemplatePopover. By default it will look for a template in $templateCache called "popoverTemplate", or specify a templte for the "content" argument. You can specify "placement" if you want the popover to appear on a certain side, or "auto" and the directive will calculate an appropriate side ("right" or "left") depending on where the element is in the window.
