FileSystem microservice: restrict file browsing locations
vtkFileSystemMicroservice has a new method
AddRootDirectory(realPath,mappedPath,location location[CLIENT|SERVER])
that
allows restricting the user of the microservice to browsing only directories
under realPath. Additionally, the paths are transformed so that mappedPath is
visible instead of realPath. This is useful if the application runs on a
server and we want to restrict the user to browse only under the provided
location and needs to hide the real system paths.
