/**
Test cases that ensure the inline examples in the project documentation
compile.
To add an example:
1. Add a test case named in the form testMGLClass or testMGLClass$method.
2. Wrap the code you'd like to appear in the documentation within the
following comment blocks:
```
//#-example-code
...
//#-end-example-code
```
3. Insert an empty Swift code block inside the header file where you'd like the
example code to be inserted.
4. Run `make darwin-update-examples` to extract example code from the test
method below and insert it into the header.
