tried to update / implement outputs and inputs according to our new
concept map, definitely will need some review with Noah as theres some
unclarity on Java particulars.
Merge branch 'master' of https://github.com/UBCSolarSimulation/Simulator.git
updated panels with primitive functions for calculating:
- power produced based on sun angle, car angle, and sun intensity
	-- finds voltage and current produced at a given temperature
	-- assumes a basic linear relationship between solar flux and watt
output
- temperature produced based on power produced
- panel efficiency based on current temperature
		-- basic linear relationship between efficiency loss and temp increase
- cooling amount based on temperature and environment temperature
		-- used basic newton laws of cooling with arbitrary constants
		
Updated Environment and Track for things required by panels
	-- included necessary getters and setters for track position, direction
	-- included necessary getters and setters for environment heat,
sunintensity, and sun angle
