/**
 * Class TWizard.
 *
 * TWizard splits a large form and presents the user with a series of smaller
 * forms to complete. TWizard is analogous to the installation wizard commonly
 * used to install software in Windows.
 *
 * The smaller forms are called wizard steps ({@link TWizardStep}, which can be accessed via
 * {@link getWizardSteps WizardSteps}. In template, wizard steps can be added
 * into a wizard using the following syntax,
 * <code>
 *   <com:TWizard>
 *      <com:TWizardStep Title="step 1">
 *          content in step 1, may contain other controls
 *      </com:TWizardStep>
 *      <com:TWizardStep Title="step 2">
 *          content in step 2, may contain other controls
 *      </com:TWizardStep>
 *   </com:TWizard>
 * </code>
 *
 * Each wizard step can be one of the following types:
 * - Start : the first step in the wizard.
 * - Step : the internal steps in the wizard.
 * - Finish : the last step that allows user interaction.
 * - Complete : the step that shows a summary to user (no interaction is allowed).
 * - Auto : the step type is determined by wizard automatically.
 * At any time, only one step is visible to end-users, which can be obtained
 * by {@link getActiveStep ActiveStep}. Its index in the step collection is given by
 * {@link getActiveStepIndex ActiveStepIndex}.
 *
 * Wizard content can be customized in many ways.
 *
 * The layout of a wizard consists of four parts: header, step content, navigation
 * and side bar. Their content are affected by the following properties, respectively,
 * - header: {@link setHeaderText HeaderText} and {@link setHeaderTemplate HeaderTemplate}.
 *   If both are present, the latter takes precedence.
 * - step: {@link getWizardSteps WizardSteps}.
 * - navigation: {@link setStartNavigationTemplate StartNavigationTemplate},
 *   {@link setStepNavigationTemplate StepNavigationTemplate},
 *   {@link setFinishNavigationTemplate FinishNavigationTemplate}.
 *   Default templates will be used if above templates are not set.
 * - side bar: {@link setSideBarTemplate SideBarTemplate}.
 *   A default template will be used if this template is not set.
 *   Its visibility is toggled by {@link setShowSideBar ShowSideBar}.
 *
 * The style of these wizard layout components can be customized via the following style properties,
 * - header: {@link getHeaderStyle HeaderStyle}.
 * - step: {@link getStepStyle StepStyle}.
 * - navigation: {@link getNavigationStyle NavigationStyle},
 *   {@link getStartNextButtonStyle StartNextButtonStyle},
 *   {@link getStepNextButtonStyle StepNextButtonStyle},
 *   {@link getStepPreviousButtonStyle StepPreviousButtonStyle},
 *   {@link getFinishPreviousButtonStyle FinishPreviousButtonStyle},
 *   {@link getFinishCompleteButtonStyle FinishCompleteButtonStyle},
 *   {@link getCancelButtonStyle CancelButtonStyle}.
 * - side bar: {@link getSideBarStyle SideBarStyle} and {@link getSideBarButtonStyle SideBarButtonStyle}.
