One-line Summary: Additions of ion and electron equations
Purpose of changes:
Add the ability of model to calculate electron and ion temperature as
well as heating of neutral atmosphere due to collision with thermal electrons
and ions.

List all existing files that have been modified, and describe the changes:
The following module has been modified for all CAM/WACCM/WACCMX run modes:
M models/atm/cam/src/chemistry/waccm_mozart/mo_jshort.F90
- fixed bug in slant_col (setting scale height for extended model and bug in
column increment calculation) and calc_o2srb (filling edge of table values)
routines
The following modules have been modified for WACCMX run mode only:
M models/atm/cam/src/chemistry/waccm_mozart/chemistry.F90
