For example, if the filepath is `/my/awesome/project/foo.bar`,
and the base directory is `/my/awesome/project/`,
then this function should return `foo.bar`.
path.relative() does something similar, but it requires a baseDir (`from` argument).
This function makes it optional and just removes a leading slash if the baseDir is not given.
It does not take into account symlinks (for now).
@param {string} filepath Path to convert to relative path. If already relative,
it will be assumed to be relative to process.cwd(),
converted to absolute, and then processed.

If not provided, all this function will do is remove
a leading slash.

] | The google.auth.getClient method creates the appropriate type of credential client for you,
depending upon whether the client is running in Google App Engine, Google Compute Engine, a
Managed VM, or on a local developer machine. This allows you to write one set of auth code that
will work in all cases. It most situations, it is advisable to use the getClient method rather
than creating your own JWT or Compute client directly.
Note: In order to run on a local developer machine, it is necessary to download a private key
file to your machine, and to set a local environment variable pointing to the location of the
file. Create a service account using the Google Developers Console using the section APIs & Auth.
Select "Generate new JSON key" and download the resulting file. Once this is done, set the
GOOGLE_APPLICATION_CREDENTIALS environment variable to point to the location of the .json file.
