   - [x] Add *level* CLI option to specify compression level for above algorithms
   - [x] Add CSV writer, which will write test results to file and test function taking folder with test files to parse.
 - **DEADLINE 04.03.2019**
+- [ ] Describe what is compression ratio, how are we calculating it.
 - [ ] Write about Z-Curve order, plot Z-Curve comparsion with normal order.
 - [ ] Plot/into tables, BPP (Bits Per Pixel), Compression throughput (MB/s).
+- [ ] Plot how are different frames compressed, x axis -> frame, y axis -> compression ratio
 - [ ] Benchmark B^3D cuda library
 - [ ] Look at *Image difference*
   - Negative values can be mapped to odd/even numbers. But the difference must be saved in more than one byte.

 ## Image difference
 - Find difference between included images.
 - Plot those differences and find out if certain images aren't same, just positioned little bit differently
