-/**

- * TTemplate implements PRADO template parsing logic.

- * A TTemplate object represents a parsed PRADO control template.

- * It can instantiate the template as child controls of a specified control.

- * The template format is like HTML, with the following special tags introduced,

- * - component tags: a component tag represents the configuration of a component.

- * The tag name is in the format of com:ComponentType, where ComponentType is the component

- * class name. Component tags must be well-formed. Attributes of the component tag

- * are treated as either property initial values, event handler attachment, or regular

- * tag attributes.

- * - property tags: property tags are used to set large block of attribute values.

- * The property tag name is in the format of prop:AttributeName, where AttributeName

- * can be a property name, an event name or a regular tag attribute name.

- * - directive: directive specifies the property values for the template owner.

- * It is in the format of &lt;% property name-value pairs %&gt;

- * - expressions: expressions are shorthand of {@link TExpression} and {@link TStatements}

- * controls. They are in the formate of &lt;= PHP expression &gt; and &lt; PHP statements &gt;

- * - comments: There are two kinds of comments, regular HTML comments and special template comments.

- * The former is in the format of &lt;!-- comments --&gt;, which will be treated as text strings.

- * The latter is in the format of &lt;%* comments %&gt;, which will be stripped out.

- *

- * Tags other than the above are not required to be well-formed.

- *

- * A TTemplate object represents a parsed PRADO template. To instantiate the template

- * for a particular control, call {@link instantiateIn($control)}, which

- * will create and intialize all components specified in the template and

- * set their parent as the control.

- * TThemeManager class

- *

- * TThemeManager manages the themes used in a Prado application.

- *

- * Themes are stored under the directory specified by the

- * {@link setBasePath BasePath} property. The themes can be accessed

- * via URL {@link setBaseUrl BaseUrl}. Each theme is represented by a subdirectory

- * and all the files under that directory. The name of a theme is the name

- * of the corresponding subdirectory.

- * By default, the base path of all themes is a directory named "themes"

- * under the directory containing the application entry script.

- * To get a theme (normally you do not need to), call {@link getTheme}.

- *

- * TThemeManager may be configured within page service tag in application

- * TTheme class

- *

- * TTheme represents a particular theme. It is merely a collection of skins

- *

- * Each theme is stored as a directory and files under that directory.

- * The theme name is the directory name. When TTheme is created, the files

- * whose name has the extension ".skin" are parsed and saved as controls skins.

- *

- * A skin is essentially a list of initial property values that are to be applied

- * to a control when the skin is applied.

- * Each type of control can have multiple skins identified by the SkinID.

- * If a skin does not have SkinID, it is the default skin that will be applied

- * to controls that do not specify particular SkinID.

- *

- * Whenever possible, TTheme will try to make use of available cache to save

- * the parsing time.

- *

- * To apply a theme to a particular control, call {@link applySkin}.
