[MARMAM] Update to SOCPROG

A new and updated version of SOCPROG, SOCPROG2.9 (both compiled and uncompiled downloads) is available at: http://whitelab.biology.dal.ca/SOCPROG/social.htm SOCPROG is a MATLAB-based package of programs for the analysis of animal social structures, movements and populations. The compiled version does not need MATLAB itself. This version is compatible with MATLAB2018b (although it will likely work well on recent and soon-to-be-released versions of MATLAB). It fixes a few bugs and adds functionality compared to previous versions (especially association complexity). Thanks Hal Whitehead, Dalhousie University, Canada
