Summary:
Adds module size as `fb_`-prefixed node attributes to the digraph output of dependencies.
The list of edges is now followed by a list of node declarations, that use the `fb_size` attribute to expose the module size in bytes.
E.g:
```
digraph {
"a" -> "b";
"b" -> "c";
"a"[fb_size=123];
"b"[fb_size=456];
"c"[fb_size=789];
}
```

Summary:
Resolves https://github.com/facebook/metro-bundler/issues/27
**Summary**
There is an edge case where tools like react-primitives need to assign to `Platform.OS`,
but the inline transformation results in an invalid AST.
When Platform.OS is unconditionally inlined, the following scenario:
````
Platform.OS = 'ios';
````
Is transformed to:
```
"ios"="ios"
````
And results in error `Property left of AssignmentExpression expected node to be of a type ["LVal"] but instead got "StringLiteral"**`.
See issue in react-primitives: https://github.com/lelandrichardson/react-primitives/issues/79
This patch checks whether the current node is on the left hand side of an AssignmentExpression
and skips the inlining when this is the case.
It also does the same for `process.env.NODE_ENV`, which suffers from the same problem. See related closed issue https://github.com/facebook/react-native/issues/7607#issuecomment-221425153 which was resolved by using bracket notation `process.env["NODE_ENV"]` instead.
**Test plan**
Unit tests included.
**Notes**
This is my first contribution to Metro, and haven't worked with Babel AST a lot, so constructive feedback on the implementation is welcome.

Summary:
In order to aid with debugging inline requires we add a method that
will give us the modules.
**Summary**
I was looking for a way to see what modules had been loaded when I was working with inline requires. I had tried using beginEvent on Systrace, but I was worried that there were modules that I might have missed (I'm not certain if all the loaded files are polyfills before the entryFile is invoked for instance). By adding getModules() it simplifies seeing what modules are loaded.
**Test plan**
At the root of my app `index.ios.js`:
```
import App from './App';
import { AppRegistry } from 'react-native';
AppRegistry.registerComponent('App', () => App);
// after 3 seconds the initial app data should have loaded, so lets take a look:
setTimeout(() => {
console.log(require.getModules());
}, 3000);
```
**NOTE**
If there is a way to get to this easily (via the debugger or some other mechanism) I would be happy to use that instead and add documentation for it.

Summary:
**Summary**
This is the workaround that cpojer suggested in #65 and should resolve the biggest pain point that developers are experiencing in that issue: using moment.js in React Native. Hopefully this at least serves as a starting point to reaching a decent solution for libraries using non-static `require()` statements.
**Test plan**
- Expected error when non-static-argument-based `require()` is nested more than one level deep within a `try` statement
- Expected no error when non-static-argument-based `require()` is nested directly within a `try` statement

Hi,
**Summary**
This fixes#40 where bundler cannot resolve a file starting with `.` from the root package directory.
it just adds a check to see if the absolute path filename is the same as the localpath filename then lets it through.
**Test plan**
- Steps to reproduce have been written up in #40
Thanks!

Summary:
Whitelist node opt `--max-old-space-size` for JSTransformer.
Bundling can choke on the default node memory settings for those of us generating large index.js files. This change allows supplied node options to make it through to the node processes spawned by the JSTransformer worker farm.

Summary:
Add useful information in the README, as an initial first version. Not all of the fields are explained, and we still miss some useful bullet points (e.g. how to release), but that should be good to give some initial guidance as a standalone project.

Summary:
Addresses https://github.com/facebook/metro-bundler/issues/62
Apparently with some versions of `jest-haste-map`, the nested source file returns the module wrapped with `default` instead of the exports themselves (due to some ES6 babel transform, I am guessing). I wasn't able to reproduce this myself yet, but I think a good first step is to avoid using nested library files in the first place, ie. only use what's exported at the top-level.
