temprorary fix for tutorial doing seismometer correction based on old
IRIS web services. Whole section needs refactoring.. :(
Catalog.plot(): use builtin example catalog and add plot example to docs
correct example catalog quakeml file from neries (has depth in
kilometers)
refactor event plot into reusable basemap/scatter plot routine (for
inventory plots)
Linear image on non-linear axis.

Employing a trick to get rid of the warning when using imshow() on
non-linear axis. The results are identical but I guess more correct and
no more warning is raised. See #748.
Replacing imshow() with proper logarithmic plotting.
Replacing TFMisfit plotting with proper logscale plotting.
Ensure some counts are really integers.
Force plotted trace type to be float.
Merge branch 'releases'
Fixing travis for now.
should fix travis failing on py2.6
Merge remote-tracking branch 'upstream/master' into event_plot_refactor
just warn on missing basemap (to make rest of imaging test suite run properly)
renaming imaging.basemap to imaging.maps
Catalog.plot(): `show` and `outfile` options
Catalog.plot(): adjust axes limits and title placement
Catalog.plot(): add image tests
Catalog.plot(): more examples in API docs
