Package Template for a Project Using Cython

This is a package template for a Python project using Cython. There are many different ways to build cython extensions within a project, as seen in the Cython documentation, but the best way to integrate Cython into a distributed package is not always clear.

This template borrows utility scripts used in the scipy and scikit-learn projects, which give the template a few nice features:

• Cython is required when the package is built, but not when the package is installed from a distributed source. That means that cython-generated C code is not included in the git repository, but is automatically included in any distribution. Further, it means that Cython is a requirement for package developers, but not for package users.
• The __check_build submodule includes scripts which detect whether the package has been properly built, and raise useful errors if this is not the case. This is especially important for when users try to import the package from the source directory without first building/compiling the cython sources.

Note that any "*.pyx" files added to the repository will have to be explicitly added to the setup.py file within the same directory: in most cases you should be able to simply copy the example setup.py within this repository.
