find_ragone_optimum()

def SUAVE.Methods.Power.Battery.Ragone.find_ragone_optimum.find_ragone_optimum	(		battery,
			energy,
			power
	)

Uses Brent's Bracketing Method to find an optimum-mass battery based on the 
specific energy and specific power of the battery determined from the battery's ragone plot.

Assumptions:
Specific power can be modeled as a curve vs. specific energy of the form c1*10**(c2*specific_energy)

Inputs:
energy            [J]
power             [W]
battery.
  specific_energy [J/kg]               
  specific_power  [W/kg]

    constant_1    [W/kg]
    constant_2    [J/kg]
    upper_bound   [J/kg]
    lower_bound   [J/kg]
            
Outputs:
battery.
  specific_energy [J/kg]
  specific_power  [W/kg]
  mass_properties.
    mass           [kg]

find_ragone_properties()

def SUAVE.Methods.Power.Battery.Ragone.find_ragone_properties.find_ragone_properties	(		specific_energy,
			battery,
			energy,
			power
	)

determines mass of a battery based on the specific energy, energy required, and power required,
works by calling find_specific_power and initialize_from_energy_and_power
Assumptions:
None

Inputs:
energy            [J]
power             [W]
