+ * TContentPlaceHolder class

+ * TContentPlaceHolder reserves a place on a template where a {@link TContent}
+ * control can inject itself and its children in. TContentPlaceHolder and {@link TContent}
+ * together implement a decoration pattern for prado templated controls.
+ * A template control (called content control) can specify a master control
+ * whose template contains some TContentPlaceHolder controls.
+ * {@link TContent} controls on the content control's template will replace the corresponding
+ * {@link TContentPlaceHolder} controls on the master control's template.
+ * This is called content injection. It is done by matching the IDs of
+ * {@link TContent} and {@link TContentPlaceHolder} controls.
