vertical marker lines for record sections

[carltape]

In some cases it is nice to see reference lines that are specified by the user. For example, in the following record section, we want to plot the origin times four different earthquakes:

So the user specifies four absolute times, and IF the record section settings do not contain any requested moveouts (e.g. variable time shifts applied to seismograms), then the plot will display vertical lines. In this example, it helps show that many of these waveforms are associated with triggered earthquakes that are designated by the user-entered times. Thanks!

This is addressed in the latest devel branch. See #73 for how to implement

@bch0w the above mentioned commit does address the issue if the input tmarks are provide in time units of seconds from the reference origin time. It seems that tmarks inputs in UTCDateTime format are not yet handled though. I can see the utility of such an option especially when studying triggered events and aftershocks. I can see that this can be easily done on the user side as well, so I wanted to open this up for discussion.

@aakash10gupta This might get tricky when mixing absolute/UTC time markers with time shifts, since any trace with a time shift now has a different definition of T=0. For a standard, distance sorted, no time-shift record section, I agree this is will be easy, but it quickly gets complicated when trying to account for time shifts and all available sorting options.

I think @carltape Matlab scripts have a curved line that shows the time-shifted tmarks? I can see that working in most cases but it may take some trial and error to find an optimal implementation.

I will re-open this issue since this feature is not as fully-implemented as desired.
