python3 /bokeh based spm image viewer
this is for viewing directories of sxm files simultaneously in real space
install anaconda because it comes with bokeh: http://bokeh.pydata.org/en/latest/
install "nanonispy" library: https://github.com/underchemist/nanonispy
invoke a bokeh server using either "all_file_viewer" or "single_file_viewer":
from your terminal: -> bokeh serve --show all_file_viewer.py
or, as another example: -> bokeh serve --port 5007 single_file_viewer.py --log-level=debug
all_file_viewer and single_file_viewer are just two instances of invoking the "widgets" and functionality assembled in "core_functions".
"nanonispyfit" contains fitting functions that can be applied to entire images; functions defined there are auto-populated into the all_file_viewer and single_file_viewer gui instances.
