/**
 *  BeforeAfterWrapper
 *    An alternative for the ::before and ::after css pseudo-elements for
 *    components whose styles are defined in javascript instead of css.
 *
 *  Usage: For the element that we want to apply before and after elements to,
 *    wrap its children with BeforeAfterWrapper. For example:
 *
 *                                            <Paper>
 *  <Paper>                                     <div> // See notice
 *    <BeforeAfterWrapper>        renders         <div/> // before element
 *      [children of paper]       ------>         [children of paper]
 *    </BeforeAfterWrapper>                       <div/> // after element
 *  </Paper>                                    </div>
 *                                            </Paper>
 *
 *  Notice: Notice that this div bundles together our elements. If the element
 *    that we want to apply before and after elements is a HTML tag (i.e. a
 *    div, p, or button tag), we can avoid this extra nesting by passing using
 *    the BeforeAfterWrapper in place of said tag like so:
 *
 *  <p>
 *    <BeforeAfterWrapper>   do this instead   <BeforeAfterWrapper elementType='p'>
 *      [children of p]          ------>         [children of p]
 *    </BeforeAfterWrapper>                    </BeforeAfterWrapper>
 *  </p>
 *
 *  BeforeAfterWrapper features spread functionality. This means that we can
 *  pass HTML tag properties directly into the BeforeAfterWrapper tag.
 *
 *  When using BeforeAfterWrapper, ensure that the parent of the beforeElement
 *  and afterElement have a defined style position.
