I need to look at histograms inside a ROOT file, but all the old ways for doing this no longer work. (in theory I can scp the ROOT file to 
the computer I am sitting in front of, but this assumes I have a working ROOT there. anyhow it is pointless to fight this, all modern 
packages are written to only work on the developer's laptop).

- root new TBrowser starts a web server, tries to open firefox (and fails)
- root --web=off new TBrowser using ssh X11 tunnel no longer works, ROOT X11 graphics refresh is broken
- macos root binary kit is built without X11 support, root --web=off does not work at all
- root7 recommended "rootssh" prints an error message (and fails)

What does work well is JSROOT which we use to look at manalyzer live histograms (through apache and mhttpd web proxies).

So I wrote mjsroot.exe. It opens a ROOT file and starts JSROOT to look at it (plus a bit of dancing around to make it actually work):

mjsroot.exe -R8082 root_output_files/output00371.root

To actually see the histograms:

a) if you sitting in front of the same computer, open http://localhost:8082
b) if you are somewhere else, start an ssh tunnel: ssh daq13 -L8082:localhost:8082, open http://localhost:8082
c) if daq13 is running mhttpd, setup http proxy:
set ODB /webserver/proxy/mjsroot to http://localhost:8082
open https://daq13.triumf.ca/proxy/mjsroot/
also
set ODB /alias/mjsroot to "/proxy/mjsroot/"
reload MIDAS status page, observe "mjsroot" in listed in the left-hand side, open it.
