 #### Creating a project
 All you need to create a project is a globally unique project ID.  You can also optionally attach a non-unique name and labels to your project. Read more about naming guidelines for project IDs, names, and labels [here](https://cloud.google.com/resource-manager/reference/rest/v1beta1/projects). To create a project, add the following imports at the top of your file:

-Note that the values of the project you pass in to `replace` overwrite the server's values for non-read-only fields (`projectName` and `labels`). For example, if you create a project with `projectName` "some-project-name", and then call replace using a `ProjectInfo` object that didn't set the `projectName`, then the server unsets the project's name. The server ignores any changes to the read-only fields `projectNumber`, `lifecycleState`, and `createTime`. The `projectId` cannot change.
