Build fails because of missing dependency fairmetadata4j

[bencomp]

I tried building the FAIRDataPoint using Maven, but it failed with the following message:

It turned out that after cloning fairmetadata4j and running mvn install in the directory, I could build the FDP WAR file.

Perhaps this step can be documented in the README? (Alternately, if the other project were published in the Maven repository, FDP should have built as well.)
