[Polyworld-develop] bct now required

[Larry Y. <la...@in...>]

I've just checked in code that means the C++ version and Python 
wrapper for the Brain Connectivity Toolbox are now required to run 
CalcMetricsOverRecent.

Get the bct-cpp code, plus instructions to build and install here:

http://code.google.com/p/bct-cpp/

After doing 'make' and 'sudo make install', also follow the 
instructions to build the Python wrapper ('make swig') and either 
copy the bct.py and _bct.so files into .../polyworld/scripts/ or put 
them wherever system-level Python modules get installed on your 
system.  (Eventually bct.py and _bct.so should be installed at the 
system level automatically.)
