Added getter for failedClasses in BaseEntryPointCreator, so that the user can handle these classes by his own.
DefaultEntryPointCreator will now not call a method the classLocal is null (no suitable cunstructor found) to avoid NullPointerException
Added check for static target method
Merge pull request #14 from florian-kuebler/develop

Allows the library user to handle classes/methods where the EntryPointGenerators failed by his own.
