David Majda 5460a881af Error handling: Implement the |error| function 
The |error| function allows users to report custom match failures inside
actions.

If the |error| function is called, and the reported match failure turns
out to be the cause of a parse error, the error message reported by the
parser will be exactly the one specified in the |error| call.

Implements part of #198.

PEG.js Spec Suite
=================

This is the PEG.js spec suite. It ensures PEG.js works correctly. All specs
should always pass on all supported platforms.

Running in a browser
--------------------

  1. Make sure you have Node.js and all the development dependencies specified
     in package.json installed.

  2. Run the following command in the PEG.js root directory (one level up from
     this one):

       make browser

  3. Start a web server and make it serve the PEG.js root directory.

  4. Point your browser to an URL corresponding to the index.html file.

  5. Watch the specs pass (or fail).

If you have Python installed, you can fulfill steps 3 and 4 by running the
following command in the PEG.js root directory

  python -m SimpleHTTPServer

and loading http://localhost:8000/spec/index.html in your browser.

Running from a command-line
---------------------------

  1. Make sure you have Node.js and all the development dependencies specified
     in package.json installed.

  2. Run the following command in the PEG.js root directory (one level up from
     this one):

       make spec

  3. Watch the specs pass (or fail).
