* Select2 widgets in Bootstrap Input Groups
*
* When Select2 widgets are combined with other elements using Bootstrap 3's
* "Input Group" component, we don't want specific edges of the Select2 container
* to have a border-radius.
*
* In Bootstrap 2, input groups required a markup where these style adjustments
* could be bound to a CSS-class identifying if the additional elements are appended,
* prepended or both.
*
* Bootstrap 3 doesn't rely on these classes anymore, so we have to use our own.
* Use .select2-bootstrap-prepend and .select2-bootstrap-append on a Bootstrap 3 .input-group
* to let the contained Select2 widget know which edges should not be rounded as they are
* directly followed by another element.
