Touchstone exists for simplereverse but is never checked

In the test case simplereverse, a touchstone directory exists but it seems the last time it was updated was 2012 and is not actually part of the current test suite.

Specifically, in the simplereverse run.sh script, there is only the command to run train/identify for segway. The program does not to enter the run directory and compare with the touchstone afterwards:

#!python

...

# seed from python -c "import random; print random.randrange(2**32)"
SEGWAY_RAND_SEED=4014068903 segway "$cluster_arg" \
    --include-coords="../include-coords.bed" \
    --track=testtrack1A,testtrack1B --track=testtrack2A,testtrack2B \
    --num-labels=4 --reverse-world=1 \
    train "../simpleconcat.genomedata" traindir

segway "$cluster_arg" --include-coords="../include-coords.bed" \
    identify "../simpleconcat.genomedata" traindir identifydir
