Based off the API documentation, one should be able to get all the users, a specific user or create a new user. This can be solved with the following two cmdlets:

Get-CloudiQUser New-CloudiQUser

This feature will be considered complete when one is able to:

• Get users
• Get user by id
• Get user by username
• Create user
