Requires all given ParseExpressions to be found in the given order. Expressions may be separated by whitespace. May be constructed using the '+' operator. May also be constructed using the '-' operator, which will suppress backtracking.

Example:

   integer = Word(nums)
   name_expr = OneOrMore(Word(alphas))

   expr = And([integer("id"),name_expr("name"),integer("age")])
   # more easily written as:
   expr = integer("id") + name_expr("name") + integer("age")
