IDAPython runtime documentation

We define the "IDAPython runtime documentation" as the documentation that's available through Python's help() system, while the user is interacting with IDAPython during an IDA session.

That documentation is SWiG-generated + patched, or custom written.

Custom-written documentation

Some functions have custom-written documentation (check for tags in the pywraps/ directory), but the general case is that the documentation is automatically generated by SWiG, and then patched.

SWiG-generated + patched documentation

Because SWiG doesn't know about the C++ SDK header's documentation, we need a way to "import" that documentation into IDAPython.

That's done by tools/inject_pydoc.py which deserves its own documentation
