/**
 * TContent class
 *
 * TContent specifies a block of content on a control's template
 * that will be injected at somewhere of the master control's template.
 * 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.
