Why move "Python Primer" before the above "PythonScript Overview "

• Code examples in Python Primer (pythonprimer.rst) are much, much simpler than in Intro to PythonScript (as they contain very little PythonScript-specific detail). Especially than Handling notifications / callbacks.
  • In particular, it introduces functions that uses functions, which is used in "callbacks"
• So it will help those who are new to Python; those who know it - will skip.
• Once python-basics are behind, the topics will flow uninterrupted focusing on pythonscript-specific topics
