loggerApp Example

The logger main application is an example that you can use to rebuild the logger application.

Building this example will create a duplicate of the logger execuable with a different name (e.g. loggerAppDIS.exe versus loggerDIS.exe). Because it is the same executable as the logger, the pre-built executable is excluded from the release.

The Qt Toolkit is required to build the logger application.
