Global Variables for template system

[eluser]Unknown[/eluser]
The problem:

I want to have a set of global variables so designers can easily put the variable in the template.
I want to be able to have Welcome user John Doe on every template page.
I use $this->load->view('template', $data) to load the template.


I have a model that is auto loaded the searches the session cookie to get the username.

thanks,
Carlos M
