Adding files for cocoapods support

-Added a preliminary LICENSE file, where the author name MUST still be added (instead of placeholder OWNER_NAME_HERE):
```ruby
Copyright (c) 2014 OWNER_NAME_HERE
```
-Also added YCameraView.podspec. In this last file, the author must be changed too, since I only added it as "yuvirajsinh" with no email, as:
```ruby
  s.author             = "yuvirajsinh"
``` 
-Tagged git repo to have a version number as 0.0.1, since CocoaPods makes use of version tags.
-last step should be to actually publish this (when everything's in order) into the Specs repo for availability directly via Cocoapods (http://guides.cocoapods.org/making/making-a-cocoapod.html) , but for now it can be added via the following Podfile directive:
```ruby
pod 'YCameraView', :git => 'https://github.com/yuvirajsinh/YCameraView.git'
```
