  This library helps you deal with boolean expressions and algebra with variables
  and the boolean functions AND, OR, NOT.
  
  You can parse expressions from strings and simplify and compare expressions.
  You can also easily create your custom algreba and mini DSL and create custom
  tokenizers to handle custom expressions.
