/*
What happens?
- `new Type().what` is looked up with a call to `get` on the proxy
- a function is returned that will look up `METHOD_NAME` when called
- `METHOD_NAME` is called because of the `()` behind `new Type().what`
- if `METHOD_NAME` exists on you object, your own function is called
- if not, because of prototypal inheritance, `get` is called again
- `name` is now `METHOD_NAME` and we can throw as we know `METHOD_NAME` is not implemented on the type

Convert SVN Repositories to Git Repositories

This guide on how to convert an SVN repository to a git repository was mostly taken from John Albin Wilkins post on Converting a Subversion repository to Git.

1. Retrieve a list of all Subversion committers

loverde

function toJSON(node) {
  node = node || this;
  var obj = {
    nodeType: node.nodeType
  };
  if (node.tagName) {
    obj.tagName = node.tagName.toLowerCase();
  } else
  if (node.nodeName) {
    obj.nodeName = node.nodeName;
