This class implements a Sample located on the grid.
This sample is (somewhat) special, in that it doesn't contain a file list per se. Instead it relies on its meta-data entries to identify a grid dataset or dataset container, and a pattern for the files to use within.
The main purpose as such is to pass it as an input sample into the EL::GridDriver. However, in practice one can still use this like a regular sample (using direct access via FAX, or pre-loading via rucio).
Normally you will not create these samples directly, but rely on the various data discovery methods, or one at a time via addGrid()
