rm unused logsumexp function
start the track determination at the orbit through the first point of the track and then iterate the track calculation to get closer to it; part of dealing with #194
automatically determine an appropriate value for nTrackIterations
#194: fix iteration for multi; plot the model track and the actual track in angle,frequency
deal w/ new trackts
rm expected failure, as the #194 test now passes
fix attribute error
rm print
add test based on MWPotential2014
mv tests to back of the queue
add multi test of nTrackIterations > 0 setup, #194
