The type of the message.
The type of a message should be related directly to its actual
							runtime type. This means that type can and will be used to cast
						the message to the relevant derived Message subtype.
Conflate this message with another OptionEvalMessage
User code should not call this function!
This means that any Option Eval Messages delivered synchronously within the same loop will be conflated with one another- that is, their state will be merged and only a single message will be delivered to the widget.
Generated using TypeDoc
A message sent when options are evaluating.
Notes
The messages contain state info about what options are being evaluated, or have finished evaluating.
