Create mat v6 files with only necessary variable

Create mat v6 files containing only the variable necessary to the
script `survival.py`. Motivations: reduce time for saving to v6,
reduce storage, reduce time for loading in Python.

Convert_Matlab/survival.m

+% This is a Matlab script. This script converts to Matlab v6 format
+% some output of TOEddies: what is necessary for the script
+% survival.py.
