Description
I spent a few hours trying to find which data within ofEasyCam needed to be load / saved to disk to save and restore a view.
I found it pretty unclear ( due to the multiple levels of inheritance ), where this core data lies.
In the end I resorted to memcpy-ing the entire object to a buffer and writing it to disk as a binary file.
This works well for my needs - but maybe we could make it a little easier? :)
This could relate to ofParameter and ofParamList->serialize() or something like that.

Research direction
Start by tracing the ofEasyCam and ofCamera inheritance, then review the mentioned ofParameter and ofParamList serialization APIs. Determine which camera state must be persisted and define a stable save/load approach; done means a documented way to restore a view without copying the whole object as binary data.
