Description
/home/travis/build/UCL/STIR/src/include/stir/RegisteredParsingObject.h:129:51: warning: instantiation of variable 'stir::QuadraticPrior<float>::registered_name' required here, but no definition is available [-Wundefined-var-template]
Possible solution seems to imply we need to define registered_name for every type, not with a template.
