Spaces are Archbee's highest organization and categorising mechanism.
Each space has a document tree that contains documents, and each documents can have 0-n children documents.
Each account created has a Private space which is specific only to that account.
Each account is associated to a workspace which has by default: General, Templates and Archives spaces, which are visible to all members of that team.
Each workspace also has the possibility of creating custom spaces, which are also visible to all members of that workspace.
