Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
- undo redo now works fine for both measure tool creation commands - added LayerHolder to streamline layer index management - added overloads for ORTHANC_ASSERT with no string message (some heavy preprocessor wizardry in there) - fixing wasm BasicScene is *not* finished.
