csvr does not make the same assumptions about mmap availability as _compact.py

Line 234 in 3f1d14a

import mmap

mmap is not available on Google App Engine - this issue was previously thought fixed with #41 but I hadn't tried to read a CSV at the time.

Can we check if it's running on App Engine as well as PY27 and above? From the docs, the environment variable SERVER_SOFTWARE will report one of two things when running on App Engine: In the development web server, this value is "Development/X.Y" where "X.Y" is the version of the runtime. When running on App Engine, this value is "Google App Engine/X.Y.Z".

I think I will do a try-catch there
