/**
* This is an abstract object that can be implied to supply
* data to be attached with a profiler marker. Most data inserted
* into a profile is stored in a circular buffer. This buffer
* typically wraps around and overwrites most entries. Because
* of this, this structure is designed to defer the work of
* prepare the payload only when 'preparePayload' is called.
*
* Note when implementing that this object is typically constructed
* on a particular thread but 'preparePayload' and the destructor
* is called from the main thread.
