title: using Codeigniter and some plugins as framework for commercial software,possible?
body: <p>i've chosen to use codeigniter as a code base for my project (commercial software)
  i've found that i can use the codeigniter in anyway (means i can use it in my commercial software) but there are some controllers and/or models i need to use too like authentications model and the template model ,am i allowed to use them in my commercial software or since it is a commercial software; making a it from scratch is more professional ? another thing; is a template model useful in my case or maybe the integrated template parser in codeigniter is enough to do the task ? there you go, edited to give more sense =]</p>
