annotate flys-artifacts/src/main/java/de/intevation/flys/artifacts/CrossSectionArtifact.java @ 2089:0da8874bd378

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Added initial state to map artifact to be able to advance and step back. The map artifact overrides describe() to have the complete UI information in the describe response document. flys-artifacts/trunk@3613 c6561f87-3c4e-4783-a992-168aeb5c3f6f
