Virtual projects #12
Description
Currently, a project is defined by a folder within the projects folder in the viewer's data directory on disk, and its files (original & processed) are contained therein. However, sometimes a user may want to create a virtual project, e.g. a project which consists of files already contained in another project. A common example would be where multiple studies are occurring on a single set of files (or different subsets of a single master set of files).
Please add the ability to create virtual projects in the viewer such that the virtual project contains all or some of the files of a different project.
