Runtime Statistics to File

[ange-yaghi]

Current Situation

• All runtime statistics are written only to the console
• This is a bit inconvenient for testing as statistics from previous runs are lost

Solution

• Runtime statistics should be saved to a file

Requirements

• This file shall be saved in workspace/render/info
• The name of the file shall match the BMP stored in workspace/render/bitmap
• Required stats are as follows:
  a. Sample count
  b. Scene description (for now just take this from the demo name)
  c. Run start-time, run end-time, total run-time
  d. All memory stats currently outputted to the console
• This functionality shall be separated from the RayTracer class (unlike the current console implementation which will soon be replaced with a more robust solution)
