/**
* HTML class for an advanced checkbox type field
*
* Basically this fixes a problem that HTML has had
* where checkboxes can only pass a single value (the
* value of the checkbox when checked). A value for when
* the checkbox is not checked cannot be passed, and
* furthermore the checkbox variable doesn't even exist if
* the checkbox was submitted unchecked.
*
* It works by prepending a hidden field with the same name and
* another "unchecked" value to the checbox. If the checkbox is
* checked, PHP overwrites the value of the hidden field with
* its value.
