[cfe-dev] python bindings

[Sam Price]

Little lost on how to add the unit tests for this feature.
I opened up tools/c-index-test.c
and looked for some similar examples

clang_getArraySize

clang_getArrayElementType

However I didn't see these calls in the c-index-test.c file.

Am I looking at the right place?  Can you provide me with
an comparable unit test to mimic?
