specify the rules for the perimeter of order visualizations

Some users should be able to visualize orders (but not actually modify or create them).

Visualizing orders can consist in

• simply listing orders and being able to view their details (is it necessary?)
• download them (in CSV format for example)
• see statistics about them

We decided that the permission should be associated with a "level", which can be "global", or a speficic GRC, or a specific accession holder.

Now, when it comes to the visualization itself, should the user always see the same perimeter, or should he/she be able to select a more precise perimeter. For example:

• if Joe can see orders at the global level, will he always download and see statistics about all the orders, or should he be able to select a specific GRC or a specific accession holder to only view/download/see statistics about orders of this specific GRC or accession holder?
• if Alice can see orders for the GRC "GRC1", will she always download and see statistics about all the orders of GRC1, or should she be able to select a specific accession holder of GRC1 to only view/download/see statistics about orders of this specific accession holder?
• should this perimeter selection, if necessary, allow the selection of multiple GRCs/accession holders, or only one?

Regarding the downloads and statistics, on which time frames should they be computed. Example possible time frames:

• the current month
• the last month
• the current year
• the last year
• the complete history
• a custom date range
