Rename Settings to ExtractorSettings so that we know what we're talking about.
Update formatting of license file so that it matches what we put in the source code.
Added a unit test that parses every XML in the resource director for the extractor tests and does a minimum amount of validation on the them.
Added a class that expands the values of properties from a java.util.Properties object into a string.
IntelliJ warned me that I had some logic that I didn't need.  Unit tests still pass.
Address issue 77 (https://github.com/TeamDewberry/jmxdatamart/issues/77) by replacing the names of system properties between ${} that appear in the "folderLocation" extractor configuration.  Note that this cleans up the fitnesse tests so that all extracted statistics are in the build "target" directory (fitnesse/target/fitnesse) so that a "mvn clean" will delete them all.
Handle expanding properties in null strings.
