annotate backend/contrib/shpimporter/floodmarks.py @ 9415:9744ce3c3853

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Rework of fixanalysis computation and dWt and WQ facets. Got rid of strange remapping and bitshifting code by explicitely saving the column information and using it in the facets. The facets also put the valid station range into their xml-metadata
