fix for IS energy levels (use keV instead of MeV when max(E)<0.1)

new example manipulate_lattice with the example of Ryoichi
some minor changes to the example
Trying again Jira.. Resolves BPWP-409

if it works should move task to state "Done"

this commits also tests jira integration
Resolves BPWP-409

An example to load a TraceWin lattice file, manipulate it, and save to a new file. See "example.py" inside the dir.

- DENSITY class updated to support ver 9.

Ryoichi noticed the issue

resembles TraceWin distribution plot

this might not work in all cases just yet

if so find them in FIELD_MAP_PATH command instead

added update_adj() which updates the lattice based on Adjusted_Values.txt

added ELEM.update() which updates element based on para

by default false. if true overwrite existing group
