<P>
A base class for defining tag handlers implementing BodyTag.
<p>
The BodyTagSupport class implements the BodyTag interface and adds
additional convenience methods including getter methods for the
bodyContent property and methods to get at the previous out JspWriter.
<p>
Many tag handlers will extend BodyTagSupport and only redefine a
few methods.
