experimental branch of sensor-native

[Stephen Bannasch]

My recent work on the sensor-native project for the sensor applet has been on the 'original-swig' branch in this github
repository.

What works well is the process to to build both a three-way Universal Mac dylib build as well as the extraction into three
separate architecture-specific dylibs.

make vernier_mac_jnilib

Creates a three-way universal dylib here:

bin/local/libvernier_ccsd.jnilib

make vernier_mac_lipo

extract architecture-specific dylibs into these directories:

bin/ppc7400
bin/i386
bin/x86_64

make vernier_mac_nar_archives
