/**
 * Method used for storing a template file.

 *        The context of the servlet calling the {@link TemplateManager} used to determine the
 *        path to store the file.
 * @param stream
 *        The inputs stream from which the template to be store is read.
 * @param name
 *        The name of the template to store. The template will be stored as:
 *        [subFolder]/name.xml
 * @param subFolder
 *        The sub-folder from the template directory defined in the properties, to store the
 *        template file in. If you specify a subFolder you need to provide a trailing slash.
 * @throws IOException
 *         If an I/O error occurs while reading from the stream.
 * @throws UnsupportedEncodingException
 *         If the encoding of the stream is not supported.
