Description of a sedflux sea-level file

A sedflux sea-level file consists of two comma-separated columns that specify sea-level with time. The first column is time (in years), and the second is elevation (in meters). sedflux uses linear interpolation to find sea-level between points. A simple sea-level file looks like this:

0   , 0
3000, -10
6000, 5

Here sea level falls 10 meters over 3000 years, and then rises 15 meters over the next 3000 years. The name of the sea-level file that sedflux uses is configured in the process description file as the sea-level module.

Note that time is measured from the start of the sedflux simulation (not, say, years before present). For example, if you are using a sea-level curve for the last 20ky, time 0 would correspond to 20ky ago and time 20ky to present day.
