/**
 * Creates an implementation of AttributeSetter for the given

 * <li>String (left as it is)
 * <li>Character/char (first character is used)
 * <li>Boolean/boolean
 * ({@link Project#toBoolean(String) Project.toBoolean(String)} is used)
 * <li>Class (Class.forName is used)
 * <li>File (resolved relative to the appropriate project)
 * <li>Path (resolve relative to the appropriate project)
 * <li>Resource (resolved as a FileResource relative to the appropriate project)
 * <li>FileProvider (resolved as a FileResource relative to the appropriate project)
 * <li>EnumeratedAttribute (uses its own
 * {@link EnumeratedAttribute#setValue(String) setValue} method)
 * <li>Other primitive types (wrapper classes are used with constructors
 * taking String)
 * </ul>
 *
 * If none of the above covers the given parameters, a constructor for the
 * appropriate class taking a String parameter is used if it is available.
 *
 * @param m The method to invoke on the bean when the setter is invoked.
 *          Must not be <code>null</code>.
 * @param arg The type of the single argument of the bean's method.
 *            Must not be <code>null</code>.
 * @param attrName the name of the attribute for which the setter is being
 *                 created.
