Re: Draft definition for _diffrn_measurement.specimen_adhesive

Here is an updated definition for the specimen attachment data names, taking into account comments from here and at Github. Further comments welcome, if none are forthcoming I will add these definitions to the core dictionary.

save_diffrn_measurement.specimen_attachment_type
_definition.id     '_diffrn_measurement.specimen_attachment_type'
_description.text
;
The way in which the sample is attached to the sample holder, including the type of adhesive material used if relevant. If
the attachment method is not included in the list below, 'Other' should be chosen and details provided in
_diffrn_measurement.specimen_attachment_special_details.

Dear Core DMG,

Please see the following proposed new definition for describing the adhesive used to attach a single crystal specimen to a capillary or other sample holder attached to a goniometer head. I have provided one definition that selects from an enumerated list, useful for machine processing, and another that allows free-form text so that brand names and other details can be included.  If you know of any methods of adhesion that are not covered in the following list, please contribute them, and if I have suggested anything that is not used in practice, please let me know.
