using comma to rename a model attribute
i'm using comma gem to download my contacts into csv format. However there's a requirement in which i'm required to rename the attribute name from first_name to First Name and i'm wondering how do i do that.

my comma DSL in my contact model is as follows

comma do

id
first_name
last_name
email
phone

end

so for first_name and last_name i'm looking for some option that would allow me to convert
first_name => "First Name" and last_name => "Last Name" something like that, any suggestions ???

By the way i'm using rails 3.1 and ruby 1.9.2
