32  * This wizard should be used as a base class for
33  * wizards that provide new plug-in templates.
34  * These wizards are loaded during new plug-in or fragment
35  * creation and are used to provide initial
36  * content (Java classes, directory structure and
37  * extensions).
38  * <p>
39  * The wizard provides a common first page that will
40  * initialize the plug-in itself. This plug-in will
41  * be passed on to the templates to generate additional
42  * content. After all templates have executed,
43  * the wizard will use the collected list of required
44  * plug-ins to set up Java buildpath so that all the
45  * generated Java classes can be resolved during the build.
