• https://github.com/LabKey/limsModules/pull/894

Changes

• should be 0.0d by default for backwards compatibility
• set emptyWellValue to Double.NaN for AssayPlateMetadataServiceImpl.parsePlateGrids
• convert Double.NaN values back to null before adding to dataRows

Manual testing notes:

• graphical import data with empty/missing values correctly appear as blank after import (not zero, non-numeric)
• I will be adding regression coverage for this in my current assay-plate-import story https://github.com/LabKey/limsModules/issues/869

@labkey-chrisj FYI, I did add selenium test coverage for this in the related PR here: https://github.com/LabKey/limsModules/pull/894/files#diff-d136e873f4845fda73ecdaa28412834d096d1007e72d706116acd591e8960e05R1094
Take a look and see if you think further testing is needed.
