/**
 * TLiteral class
 *
 * TLiteral displays a static text on the Web page.
 * TLiteral is similar to the TLabel control, except that the TLiteral
 * control does not allow child controls and do not have style properties (e.g. BackColor, Font, etc.)
 * You can programmatically control the text displayed in the control by setting
 * the {@link setText Text} property. The text displayed may be HTML-encoded
 * if the {@link setEncode Encode} property is set true (defaults to false).
 *
 * Note, if {@link setEncode Encode} is false, make sure {@link setText Text}
 * does not contain unwanted characters that may bring security vulnerabilities.
