2021-08-25Documentation: application-developer: Recommend unique_ptr for CameraManagerKieran Bingham
The CameraManager object should be deleted when it is no longer used to prevent it from leaking. When the application closes, the memory will be released, but it would show up in reports from memory validation tools such as valgrind if not handled correctly. Recommend best-practices in the guide and ensure it is automatically cleaned up when the CameraManager goes out of scope.

2021-08-25Documentation: application-developer: Clean up build instructionsKieran Bingham
The build and run instructions read as if meson is the only way to compile the application. Although this is recommended, it is not required - adapt the language to fit better. While here, fix the naming of the simple_cam meson object to match the other usages of 'simple-cam'.

2021-08-09libcamera: Rename 'method' to 'function'Laurent Pinchart
Usage of 'method' to refer to member functions comes from Java. The C++ standard uses the term 'function' only. Replace 'method' with 'function' or 'member function' through the whole code base and documentation. While at it, fix two typos (s/backeng/backend/). The BoundMethod and Object::invokeMethod() are left as-is here, and will be addressed separately.
