function PSCISqlServerUser {

    <#
    .SYNOPSIS
    Ensures specified SQL Server Logins and Users exist.
 
    .DESCRIPTION
    This function can be invoked both locally (preferred - but SQL Server port will need to be open) and remotely (-RunRemotely - without restrictions).
    It uses following tokens:
    - **SqlServerUsers** - hashtable (or array of hashtables) with following keys:
      - **ConnectionString** - (required) connection string to the database
      - **Username** - (required) name of user/login to create
      - **DbRoles** - list of database-level roles to assign to the user (db_owner, db_datawriter, db_datareader etc.)
      - **DatabaseName** - name of database where the user will be created (if not specified will be taken from ConnectionString / Initial Catalog)
      - **CreateUser** - determines whether user will be created if it doesn't exist
      - **CreateLogin** - determines whether login will be created for the user if it doesn't exist
      - **LoginWindowsAuthentication** - determines login type (Windows / SQL Server Authentication)
      - **LoginPassword** - password for login to create (only if CreateLogin = true and LoginWindowsAuthentication = false)
      - **LoginServerRoles** - list of server-level roles to assign to the login (sysadmin, serveradmin etc.)
       
    See also [[Update-SqlLogin]] and [[Update-SqlUser]].
 
    .PARAMETER Tokens
    (automatic parameter) Tokens hashtable - see description for details.
