BUG: Fix otherPrint test so that it does not segfault when trying to printself on the actor. The condition was caused because at construction time there is no input into the vtkGraphLayoutViewer class (and there doesn't have to be). Anyway actor was calling print self on it's vtkPolyDataMapper and the mapper was going a this->GetInput()->GetBounds() and this->GetInput() was NULL.

STYLE: Just some formatting changes that should have no effect on execution
