    Description

      This project is to implement a new column group for piece-wise linear compression that is based on a target loss.
      The technique compress a column of values, into smaller line segments.
      A naive implementation of this in the extreme cases would potentially be 0 target loss, with full allocation of input,
      and 100% target loss containing only the average of all values.
      Other than this the implementation moves from a lossless array into a lossless piece-wise linear
      representation via dynamic programming.
