GWT 2.8.0 compatible implementation of java.util.concurrent.CompletableFuture and supporting classes. The implementation is compatible with Java 8 lambdas. (The preceding line was really included to help those looking for such via a seach engine)
This merely packages commit nordligulv/gwt@8b17515 into a standalone library for GWT.
If/When GWT includes CompletableFuture emulation itself, this library will be obsolete.
