Commiting node_modules

In preparation for posting on stackoverflow asking how to get Require.js
to load React.js, I'm pushing the node_modules directory so that the
version of React in use is easy to examine.
Generate AMD version of React.js with r.js - still getting errors

As recommended in the Require.js documentation, I used r.js to generate
a version of React.js that is converted to using AMD module
requirements. There were several parse errors logged during the
conversion, saying that the following files were skipped:
 * react/node_modules/envify/node_modules/esprima-fb/bin/esparse.js
 * react/node_modules/envify/node_modules/esprima-fb/bin/esvalidate.js
 * react/node_modules/envify/node_modules/jstransform/node_modules/source-map/test/run-tests.js
 * react/node_modules/envify/node_modules/jstransform/visitors/__tests__/es6-rest-param-visitors-test.js
 * react/node_modules/envify/node_modules/jstransform/visitors/__tests__/es6-template-visitors-test.js

When I run a `python -m SimpleHTTPServer` and look for console errors, I
see repeatedly an error that `process is not defined`.
