complete examples for DC (SilwalTape2016) and FMT (Alvizuri2018) for Alaska earthquake

[carltape]

We need a complete example that takes the user from pyseis to cap to GMT plots that characterize the uncertainty. Let's use the Anchorage earthquake for both examples, since only one set of waveforms needs to be used. The first example should be the DC uncertainty figure in SilwalTape2016. The second example should be the FMT uncertainty figure in Alvizuri2018 (see output from catalog).
