Reminder of final step to export project file from MagNav

When you've exported a project file from MagNav onto a USB drive, be sure to choose the "Eject" function in Android before physically removing the USB drive from the MagNav tablet.  If you don't, the project database may not be correctly saved to the USB drive, and when you open it in Survey Manager you might not find any data.

A corollary to this practice is to check the data in Survey Manager before deleting a project from MagNav; there is no mechanism to un-delete a project in MagNav.

The "Eject" feature varies a little from version to version of Android, but is normally found by swiping for the main Android options menus, then finding the USB drive and tapping on a link to "Eject".
