public DataType getContainingFieldDataType() {
		return containingFieldDataType;
	}
Returns the {@link DataType} of the field that this object instance was contained inside of,
or null if this instance was not a field inside another structure.
<p>
For instance, if a structure was being deserialized because it was a field inside 
another structure, the actual Ghidra data type of the field may be slightly different
than the structure data type defined at the top of the structmapped 
class (ie. {@code @StructureMapping(structureName='struct')}.  The containing field's
data type could allow custom logic to enrich or modify this struct's behavior.
