0.3.8

Features

This release improves usability of Option with some new operations

• isEmpty to check whether the value is defined or not. It is counterpart for isDefined and aligns well w/ other structures
• tapNone to allow executing side effect when Option is none. This is handy when some logging is needed in case of empty values
• toEither direct conversion method with possible left side definition on empty.
• toArray direct conversion to empty array when Option is empty and single element array when Option is defined
• toList similar to toArray, direct conversion to empty ArrayList or single element ArrayList
