How do you create a merchant user

[rserna2010]

Example:
http://developers.finixpayments.com/#create-a-merchant-user

curl https://api-staging.finix.io/identities/IDd1pPDrudAFBb161aPMFK8n/users \
    -H "Content-Type: application/vnd.json+api" \
    -u  US9EhKMhD1L4AzvChDSwPJa3:420ff37e-d8bf-4c1c-872e-ce10a0c68ffc \
    -d '{}'

I see a method for creating an Application user but not one for identities. Can you please add if it doesnt exist or show how to below.

@rserna2010 that method is identity->provisionMerchantOn(Merchant_Object)
