def pathIsGood(p: String, conf: Configuration): Boolean

Determines if a path is 'valid' for this source.
Determines if a path is 'valid' for this source. In strict mode all paths must be valid. In non-strict mode, all invalid paths will be filtered out.
Subclasses can override this to validate paths.
The default implementation is a quick sanity check to look for missing or empty directories. It is necessary but not sufficient -- there are cases where this will return true but there is in fact missing data.
TODO: consider writing a more in-depth version of this method in TimePathedSource that looks for TODO: missing days / hours etc.
