raytracer

• integrator is broken while working on cameras
  • successfully building but error on command
  • changed private camera to pointer
  • fixed pointer to closed ofstream bug in Film::writeFrame()
    • out.ppm still doesn't have main body
• set up camera transforms and modify pixel lookup in render()
• move basic integrator into its own file and directory
• film uses shared_ptr because camera gets copied into integrator
  • pointer to camera could be a work around for this
