App log file

In the case of a side load, your going to copy a file named <myapp>.prg to the watch so the log file will be <myapp>.txt  and in the logs folder.

If you had previously installed from the app store, uninstall that first.

Sideloaded apps don't get renamed unless the manifest id matches an app installed from the store.  Normally if you are testing a completely new app the file will stay exactly how you save it.  For example you are testing NewTestApp1.prg and the app has never been in the store, then you should see it in the garmin/apps/ folder.  Then create a blank text file in garmin/apps/logs named NewTestApp1.txt.  All the println in the app will be written to that file.
