Adds additional info for creating Swift modules 

This may be common knowledge for most Swift/ObjC guys, but it took me quite a while to figure out why I was getting an error when creating/exporting my module. As a web guy coming to the "native" world, it was a bit confusing. I would imagine a lot of RCTN users will be in the same boat.

For those of you new to Swift and Objective-C, whenver you [mix the two languages in an iOS project](https://developer.apple.com/library/prerelease/ios/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html), you will also need an additional bridging file, known as a bridging header, to expose the Objective-C files to Swift. Xcode will offer to create this header file for you if you add your Swift file to your app through the Xcode `File>New File` menu option. You will need to import `RCTBridgeModule.h` in this header file.
```objc
// CalendarManager-Bridging-Header.h
#import "RCTBridgeModule.h"
```
You can also use `RCT_EXTERN_REMAP_MODULE` and `RCT_EXTERN_REMAP_METHOD` to alter the JavaScript name of the module or methods you are exporting. For more information see [`RCTBridgeModule`](https://github.com/facebook/react-native/blob/master/React/Base/RCTBridgeModule.h).
