Team Foundation Server and Xcode projects with git-tf

Introduced `git-tf`, a tool that allows users to create a local git repository from a path in Team Foundation Server and check changes back into TFS. This enables users of IDEs without built-in TFS integration, such as Xcode, to utilize TFS Version Control. The post demonstrates cloning a TFS project into a local git repository, making changes in Xcode, committing to the local git repository, and then checking those changes back into TFS. It also shows how this process integrates with Continuous Integration builds.
