        .SYNOPSIS
            Gets all user rights granted to an account
        .DESCRIPTION
            Retrieves a list of all the user rights (privileges) granted to one or more accounts. The rights retrieved are those granted directly to the user account, and does not include those rights obtained as part of membership to a group.
        .EXAMPLE
            Get-UserRightsGrantedToAccount "bilbo.baggins"
 
            Returns a list of all user rights granted to bilbo.baggins on the local computer.
        .EXAMPLE
            Get-UserRightsGrantedToAccount -Account "Edward","Karen" -Computer TESTPC
 
            Returns a list of user rights granted to Edward, and a list of user rights granted to Karen, on the TESTPC system.
        .PARAMETER Account
            Logon name of the account. More than one account can be listed. If the account is not found on the computer, the default domain is searched. To specify a domain, you may use either "DOMAIN\username" or "username@domain.dns" formats.
        .PARAMETER Computer
            Specifies the name of the computer on which to run this cmdlet. If the input for this parameter is omitted, then the cmdlet runs on the local computer.
