updated screens for loading
uncommented signature image generation

(left commented accidentally in a previous commit)
updates to pathway app and figure
prune requirements.txt

I can't find any direct dependencies for the following modules listed
in requirements.txt, so I got rid of them:

mimeparse
python-dateutil
python-ptrace
rope
ropemode

I also deleted the argparse requirement, since this module is now part
of the standard python library (the version that pip installs is
available for the benefit of older versions of python; the differences
between versions 1.2.1 and 1.1 (the one included in the standard
python library) seem to be mostly geared to compatibility with Python
3).
comment out errors in re_run.sh

The commented out code can be re-instated after the file
LCMS_HMSL10014.101.01.pdf gets commited.
layout and css tweaks
Merge remote-tracking branch 'upstream/master'
first stab at "sensitivities django-app"

...for MF's tutorial.
Merge remote-tracking branch 'main/master'
fixed picks_for_slider.tsv...

...(in sampledata/MH) so that the response time-average plot is
included in the same batch as the ones for the slider proper, and
therefore "contributes" to the computation of the common limits.

The invocation of do_scatterplots.py for this case should be changed
to

  WITHLIMITS=1 OUTPUTDIR=django/responses/static/responses/img/slider \
    python src/do_scatterplots.py sampledata/MH/picks_for_slider.tsv

Note the setting for the OUTPUTDIR global.  This setting is necessary
because otherwise the image called pakt,igf-1,100__perk,fgf1,100.png
would clobber an existing image with the same name but generated with
lims=None.
changed colormap for scatterplot to blue-white-red
removed extraneous slash after STATIC_URL in templates
do_scatterplot: nan -> 0.5

change do_scatterplot.py to arbitrarily assign a level of 0.5 whenever
the data is missing

change the input files so that missing values are specified as nan
rather than 0.0
Merge remote-tracking branch 'main/master'
scatterplot cleanups

* removed debug print
* changed url to slider image to new slider/ dir
untrack automatically built files
add nans to test scatterplots
fix small bug in do_scatterplots.sh
make DATADIR1 cl-settable
update README.txt

this version is much shorter, because it refers the user to the
do_sccatterplots.sh source for more details.
