[Opensg-core] [OpenSG 2] What is a FieldBundle ?

already received the original message]

	Hi,

Gerrits commits today suggest that FieldBundle is more than an
experiment that remained in the tree (which is what I thought it was ;) ).
I'd like to know what a FieldBundle is and how it differs from a
FieldContainer. It would be great if an explanation included the
rationale for its existence, i.e. what problem does it solve ?

	Thanks,
		Carsten

PS: The answer to this mail would probably make a nice description of
the class in FieldBundle.cpp. hint, hint ;)
