Add convenience API's for accessing blocks and instructions in Function (#792)
Add convenience API's for accessing blocks and instructions in Function (#792)

* Update export-svg.py path splitting

Changed the path splitting part to the way python's documentation recommends it.

I got some errors trying to use that function on windows, because it didn't split correctly.
I stumbled upon this in the python documentation:
https://docs.python.org/2/library/os.html#os.sep
I changed the relevant line using their recommendation.

* Rename data to session_data, as this API is per-session and not stored in the db

* get_basic_blocks_starting_at incorrectly in the docs

* Update troubleshooting.md

* Zoom

* get_instruction_low_level_il tweak

made api docs less ambiguous

* documenting Type.int and Type.function

* Update __init__.py

* Add convenience API's for accessing blocks and instructions in Function
