Find user details

1. The first step towards collecting measurement data is to know your Campbell Cloud user ID, as well as the organization ID to which your user belongs.

2. To received your user details, the following call needs to be made:

   https://api.campbellcloud.io/api_v2/user/session

3. Within the user details that are returned, the value for "kc_id" is the user ID and the value for "organization_id" is the organization ID. These will be required for future API calls.
