* Because Pods and the Podfile.lock are not checked in, they should be removed before installing. Otherwise the state is not consistant.
* Pod install no longer updates the repo
* Copy changes to split up examples.
* [Travis CI] Build Optimizations
* update cocoapods versionm
* test sharing derived data directories
* Hack to reduce travis run time
* Remove test file

In addition to building & testing AsyncDisplayKit, this new build script
can ensure that all example projects still compile. This will prevent
breaking API changes from landing without updating sample projects that
use them. It's also extensible, so we can add additional integration
tests in future (e.g., non-CocoaPods framework integration).
Don't consider the build broken if a feature branch is broken.
Move the actual build command to a separate script -- easier to read,
easier to maintain, and easier to run by hand.
