Setting user data

Before the scan the user has to define the require user data. It can be done in Spock by, e.g.

p09/door/haspp09.01 [1]: nxsetudata sample_name Water
It provides data for CLIENT datasources, i.e. sample_name=Water.

The user data can be unset by e.g. :

p09/door/haspp09.01 [1]: nxsusetudata SampleName

In the similar way a user can add her/his free-form comments, e.g.:

p09/door/haspp09.01 [1]: nxsetudata user_comment "mono was very stable"
The value of user_comment will be store in default location of NeXus file.
