David Majda 3333cdd18d Position tracking: Kill the |trackLineAndColumn| option 
Getting rid of the |trackLineAndColumn| simplifies the code generator
(by unifying two paths in the code).

The |line| and |column| functions currently always compute all the
position info from scratch, which is horribly ineffective. This will be
improved in later commit(s).

David Majda 0519d7e3ce Git repo npmization: Make the repo a npm package 
Includes:

  * Moving the source code from /src to /lib.
  * Adding an explicit file list to package.json
  * Updating the Makefile.
  * Updating the spec and benchmark suites and their READMEs.

Part of a fix for GH-32.

David Majda 0865e9e51a Make benchmark suite support |trackLineAndColumn| option 
Both the browser and the command-line version of the benchmark suite
runner now allow users to specify a value of the |trackLineAndColumn|
option. In case of the command-line version this required a minor CLI
redesign.

David Majda 11a44948ab Extract JavaScript and CSS from benchmark/index.html into separate files 
JavaScript is extracted to make it JSHintable, CSS is just for symmetry.

David Majda f0eab4728a Use Unicode box-drawing characters for command-line benchmark table 
Hopefully this works reasonably in all environments where Node.js runs.

David Majda 5ab36f8018 Split the vendor directory 
There are now three vendor directories. The goal is to have test- and
benchmark-specific stuff is its own directories and not in the main one.

  vendor
  test/vendor
  benchmark/vendor

David Majda e59f3ba338 Split the source code into several files, introduce build system 
The source code is now in the src directory. The library needs to be
built using "rake", which creates the lib/peg.js file by combining the
source files.

David Majda c3b5c2131a Benchmark: Factor benchmark into several functions run using |setTimeout| 
We do this for two reasons:

  1. To avoid bowser mechanism for interrupting long-running scripts to
     kick-in (or at least to not kick-in that often).

  2. To ensure progressive rendering of results in the browser (some
     browsers do not render at all when running JavaScript code).

This does not change the benchmark suite execution speed statistically
significantly on V8.
