This modifies setup.py to try building the cython vector first and, if that fails, installs without building that extension.
There are at least a couple of different ways that the failure can happen: user has no compiler installed (the usual case on windows) or the compiler is misconfigured, or you are building from source and forget to install cython :).

Ready to merge once the tests pass.
