A python package namespace that establishes the testcases namespace package. Other packages can use this namespace to install test cases.
Will also provide special test case support, such as documentation generators.
The devtest framework uses this as the base package name to find test cases to run.
Other package distributions may use the "testcases" base package to install additional test cases for any project.
This project may also be used as a template for other testcases packages. Since it uses the setuptools namespace feature, all such packages will have the root package name of "testcases". The framework, by default, search for test case implementations in this namespace.
