## to add a computer...
## make sure it has a data folder shared as //<machine>.phas.ubc.ca/Local_Measurement_Data
## create a mount point on the server at /mnt/<machine>
## create a new mount command, rsync command, and unmount command for <machine>

## if you want to add a new type of data file start by adding --include='*.???'
## to the rsync commands
