 * @brief An assistant for creating new source code files using Grantlee templates.
 *
 * This assistant guides the user through generating source code from templates.
 * Currently, class and unit test templates are supported.
 *
 * Depending on the selected template type (@c Class or @c Test, see SourceFileTemplate::type()),
 * The assistant creates appropriate pages for setting the required options.
 *
 * When creating a new class, an ICreateClassHelper is used for the language-specific features.
 * If no such helper exists for the chosen template, a generic implementation is used.
 * The actual generation of classes is done using a TemplateClassGenerator.
