 =========
 
 A parser-combinator library for building easy to test, read and maintain parsers using functional composition. 
 
 ### todo
- - godoc: I've been slack and the interfaces have been changing rapidly.
  - fatal errors: Some way for a parser to say "Ive found a good match, the input is broken, stop here with an error"
  - better errors: currently only the longest error is returned, but it would be nice to show all expected tokens that could follow.

 This parser will return numbers either as float64 or int depending on the literal, for this calculator we only want floats so we Map the results and type cast.

 This parser will match number ([+-] number)+, then map its to be the sum. See how the Child map directly to the positions in the parsers? n is the result of the and, `n.Child[0]` is its first argument, `n.Child[1]` is the result of the Some parser, `n.Child[1].Child[0]` is the result of the first And and so fourth. Given how closely tied the parser and the Map are it is good to keep the two together.
