+ '''A container for a morphology, plus its metadata.
+
+ A morphology is, basically, a dict. This class acts as that dict,
+ plus stores additional metadata about the morphology, such as where
+ it came from, and the ref that was used for it. It also has a dirty
+ attribute, to indicate whether the morphology has had changes done
+ to it, but does not itself set that attribute: the caller has to
+ maintain the flag themselves.
+
+ This class does NO validation of the data, nor does it parse the
+ morphology text, or produce a textual form of itself. For those
+ things, see MorphologyLoader.
