The NEWPROJECT Action starts a new project in Polybench Designer. If the previous project has not been saved, the user is warned to save the project.
This is the same as selecting 'New Project' in the File menu of Polybench Designer.
An Action may use a Value and an Address
Value: empty.
Address: empty.
If the old project has not been saved, the user is told so by the close-project dialog. Otherwise, the current project is closed and a new one begins.
