Processing Error: "Cannot convert from RadioButton to Toggle" - SOLVED

- Running osPID Front-End using Processing 1.5.1 resulted in the
  above error.

  The following page gave insight on how to fix it:
  https://forum.processing.org/topic/controlp5-and-glitchsort2

  NB: This error was never seen on another machine running an
  identical version of Processing with Front-End code as it was
  prior to this commit.

  Tested working under:
  - Processing 1.5.1
  - controlP5 1.5.2
