Folders are a hierarchy of containers for data and files. The are the place where permissions are set
in LabKey Server. The top level in a folder hierarchy is the project. Below the project is an arbitrary
hierarchy of folders that can be used to partition data for reasons of security, visibility, and organization.
Folders cut across schemas. Some schemas, like the lists schema are not visible in a folder that has no list objects
defined in it. Other schemas are visible in all folders.
