Function gpp::process_buf

pub fn process_buf<T: BufRead>(
    buf: T, 
    buf_name: &str, 
    context: &mut Context
) -> Result<String, Error>

Process a generic BufRead.

This function is a wrapper around process_line. It splits up the input into lines (adding a newline on the end if there isn't one) and then processes each line.
