added a couple checks
playing with parameters
working on using battery in hierarchical system
renamed Battery -> batteryUpdate. this is the change for 1 timestep. the current charge level is batteryCharge.
fixed horizcat bug
hierarchical batt progress. next step: add batteryCharge (current battery state) as input for HLLMS

HLLMS using input data for starting batt condition
added more plots
cleanup
