Move documentation from the \file directive to the CameraManager class,
as it documents the class, not the file. Improve the documentation to
provide a brief overview of how the camera manager operates, and fix a
few typos and inconsistencies.
The documentation mentions hotplug even though it isn't implement yet,
as this is a planned feature. More improvements are needed for the
documentation of the CameraManager member functions, and will be added
as part of the API improvements in the near future.
