- Masking out SBCommandReturnObject::Printf() from the Python layer because SWIG and varargs do not get along well.

- Providing file-like behavior for SBStream with appropriate extension write() and flush() calls, plus documenting that these are only meant and only exist for Python
Documenting the file-like behavior on our website
