input: Write a python function to convert between Celsius and Fahrenheit using a class.
  assert Temperature(0).to_fahrenheit() == 32.0
  assert Temperature(100).to_fahrenheit() == 212.0
  assert Temperature(32).to_celsius() == 0.0
  assert Temperature(212).to_celsius() == 100.0
output: class Temperature:
      def __init__(self, temperature):
          self.temperature = temperature
  
      def to_fahrenheit(self):
          return (self.temperature * 9/5) + 32
  
      def to_celsius(self):
          return (self.temperature - 32) * 5/9
