/**
|
|
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.
