Fixed automation simulation
Merge pull request #77 from sharrington93/master

Fix to current air density calculation
Merge branch 'master' into air_density

Fixed bug where motor_heat_capacity could not be modified in the GUI
Merge pull request #78 from sharrington93/save_input

Fixed bug where motor_heat_capacity could not be modified in the GUI
Fixed sea level temp and temp lapse rate so they are back to the standard values.
Corrected constants used in model
Removed test code
Merge pull request #79 from sharrington93/air_density

Air density model fixes
Fixed the removal of parameter files from a project

* Removes parameter file from project file correctly now
* Removed parameter file no longer is still ran through the simulation

Known issues:
* Possible that Simba will switch to the next parameter file in the project but not display the correct file being viewed
Final fixes for removing parameter files from a project
Merge pull request #80 from sharrington93/remove_parameters

Remove parameters
Transferred current air density equations to automation simulation.
