Replace all unvisible types by Object

[stephanenicolas]

When processing a class, it can internally use types that may not be visible in the boundbox scope or in its clients scope.

In that case , the type should be replaced by Object.

[stephanenicolas]

The visitor inside the BoundBoxScanner should take into account the visibility of the types it visits :

• a type that is public at root level is visible
• a type that is public and is an inner class of a class that is visible, is visible
• a type that is protected or package at root level and in the same package as the BoundBox class is visible
• a type that is protected or package and is an inner class of a class that is visible and in the same package as the BoundBox class is visible

TODO :

• [x] Update Annotation Processor
• [x] Fields
• [x] Methods signature : return type + param + exceptions
• [x] Inner classes
• [ ] Update wiki
• [ ] Update integration tests
• [ ] Check that package is taken into account

Typical example :

public class A {
    private class B {}
    B foo();
}

A.B is not visible from BoundBoxOfA, the signature of BoundBoxOfA.foo() should be :

 public Object foo()
