Integração phpjasper

Sorry for my english, I need help integrating phpjasper integration in CI, to make reading .jrxml files, but integration is with this class here https://github.com/cossou/JasperPHP
I did not find any reference for integration with the IC, please I need help.

I need to know how to call JasperPHP to pass the .jrxml and display on the screen.

Thank you
