Altering the Tag Body

• In the last example, we basically left the body unaltered, but we don't have to.
• Instead of extending TagSupport, we must now extend BodyTagSupport, which gives us new methods:
• doAfterBody() allows you to change the tag body.  Normally, return SKIP_BODY to let it know you are finished procesing the body.
• getBodyContent() gives us a BodyContent method that has information about the tag body.
• We'll also use some methods from the BodyContent class, given to us from getBodyContent().
• getEnclosingWriter() gives us the JspWriter that doStartTag and doEndTag use.  This is the stream to which we write the new body.
• getEnclosingReader() returns a Reader that can give us the body of the tag.
• getString() returns a String of the entire tag body.
