   5 An utilities that is used by Mint.
   6
   7 == Classes:
   8
   9 == Mint::Expression
  10 This class represents an expression.
  11
  12   expression = Mint::Expression.new('5 div 4', expression_tree)
  13   p expression.to_s #=> '5 div 4'
  14   p expression.to_maxima #=> '5 / 4'
  15   p expression.to_latex #=> '5 \div 4'
  16   p expression.normalize #=> '5 div 4'
  17
  18 == Mint::Builder
  19 This class builds expression from string.
  20
  21   input = Readline.readline('>')
  22   begine
  23     answer = Mint::Builder.build(input)
  24     p answer.class
  25     #=> Mint::Expression
  26   rescue
  27     puts 'Please check your answer.'
  28   end
  29
  30 == Mint::Generator
  31 Problem generator.
  32
  33 === Factory
  34 Factory generates problem generator.
