* Adds new file.Move func to address a bug with Golang/Docker volumes when using os.Rename Also uses TempDir for tests instead of live directories and increases test coverage for file.Write * Goimport the imports * Make usage of file package name consistent so it no longer clashes with vars * Remove outputFile if io.Copy fails
