Problem: Doxygen not picking up documentation
Problem: Doxygen not picking up documentation

Documentation generated by cbindgen is not displayed in Doxygen's
output.

Solution: use comment styles supported by Doxygen

For C, this will be

```
/**
 * ...
 */
```

For C++, this will be

```
///
/// ...
///
```

as described at http://www.stack.nl/~dimitri/doxygen/manual/docblocks.html
