Adding all new files to update the AdColony Unity SDK plug-in. These changes come with a new post process build script that integrates seamlessly with Unity's build process, and allows for the ability to build and run when targetting iOS deployments. This update also comes with package files. We now have unity packages available that should place the files in their correct hierarchy location so that you the developer will not need to worry about where they should go. This update creates a bifurcation for our provided files in that we are clearly stating what Unity versions we will support with them. I.E. Pre Unity 4.3, and post unity 4.3 versions. Lastly there are new sample apps. These apps provide more clarity for how our framework can be used. The simple apps created show very basic use cases for interacting with the AdColony plug-in, while the complex sample app shows a robust implementation example of how a developer might want to consider using our SDK. The AdManager used for the complex sample app has also been added to the packages created, as some users might find it beneficial to use that abstraction for their development purproses. This commit serves to stage the files before moving directly to the new configuration. We hope that you find these changes to your liking and that if you experience any issues, that you communicate them to us at your earliest convenience.
