* This class reads a previously saved session from disk, restoring Luppp's

*
* The directory <sessionDir> is the main point of loading. The user selects
* that directory to load the session from. <sessionDir>.luppp is the name of
* the session file: it contains all info about the session: Volumes, loaded
* samples etc.
*
* Samples are read from the directory <sessionDir>/samples, in which there is a
* sample.cfg file, which can be parsed to get sample metadata.
