* configuration.r and projects.r merged (because of cross references with one another)
* moved DialogBox into projects.r because file loading uses it
* troubleshooting dataset selection dialog... sort of working superficially now but there is a bug transmitting the selection to the rest of the system
* saveResults() renamed to saveProjectFile()
* loadDataset() method implemented (can't use readProjectFile() because it needs the projectFolder preset...)
