/**
 * TStatements class
 *
 * TStatements executes one or several PHP statements and renders the display
 * generated during the execution. The execution happens during the rendering stage.
 * The PHP statements being executed can be set via the property
 * {@link setStatements Statements}. The context of the statemenets executed
 * is the TStatements object itself.
 *
 * Note, since TStatements allows execution of arbitrary PHP statements,
 * make sure {@link setStatements Statements} does not come directly from user input.
