Comparison of the PaleoMIST 1.0 ice sheet margins, ice sheet and paleo-topography reconstruction with paleo sea level indicators

In this package, there are two reports, each of which have five model runs that are compared with the 
standard PaleoMIST 1.0 ice sheet margins, ice sheet and paleo-topography reconstruction. The first document
(report1) shows a comparison of the response using a variety of lower mantle viscosity values. The second 
document (report2) compares the standard PaleoMIST 1.0 with one where the ice load has been linearly
interpolated to 500 year time steps, the alternate reconstruction with an ice covered Hudson Bay, and
three other commonly used Earth models. The sea level data, plus the scripts used generate the report, 
can be found on Github:

I have also included the explicitly calculated sea level for all the models displayed in these
reports in a zip file called "calculated_sea_level.zip". You can place the files in the 
folder "latex/calculated_sea_level" after you download the Git repository.

Version 1.3: This release adds sea level data from Antarctica. I have also modified the appearance of plots so index points appear as rectangles rather than dots with error ranges.
