Usage: 
	flourish login [email]
	flourish login --token [token]

Log in to Flourish. You will be prompted for a password.

If you do not have a Flourish account, you can register using “flourish register”.

When you have logged in successfully, your access token will be recorded
in the file .flourish_sdk in your HOME or USERPROFILE directory. Subsequent
flourish commands will use this token to authenticate with the server.
