File:	IStreamFieldHandler
Purpose:	Used to extends context to generate code for complex/challenging fields that need
	context info
	Implemented as separate interface mainly because it is needed by very few context classes
	(This deals with the fact that the CodeWriter is not the actual visitor, but
	delegates the visiting to the ContextTree and works on the dataset, handles returned from the
	ContextTree)

Notes:	Used from CodeWriter to optionally let the context write some fields.
	The writer exports all fields not returned from WriteFieldAssignments or StatementFieldNames
	if serialize-hidden = false.
	/* Returns list of fields that need to be exported as separate statements
	This allows the writer to check what to skip from the assign statement
	(The assumption is that the general assign statement is above the )
