Added tests for CopyNotInDestination, DeleteNotInSource, SetDestMetadata, OverwriteIfNewer
Added more logging
Update package version to  beta
Changed a couple of bool params so that their default values can be false
1) Changed copyNotInDestination to skipCopyNotInDestination.
So, default value flipped from true to false
2) Renamed 'allowSAS' to 'useSAS' and changed default to false
