Code Generator for Eclipse Code

Refactoring of the headless artefact generator

Refactoring after the moving of the enumeration

Move the enumeration ch.sahtits.codegen.java.input.EHeadlessInputMethod from the plugin ch.sahits.codegen.java to ch.sahits.codegen

Use different method signatures to distinguish the methods from the interface IExtendedDBDefinitionPage and IBasicDBDefinition page instead of overriding them with a different return type. This resolves #61.

Updated the test document

Remove the Checklist lock and make use of the Debugging flags

Improved layout

Improve the generation of reference implementation classes

Refactored the class to use the extension point

Add the source foulder to the extension point
