/*=====================================
  A Blob object is a regular polygon variant that
  can have various features.
  Instance Variables:
    numSides: number of sides
    radius: distance from the center of the polygon
      to any vertext
    x: x coordinate of the center
    y: y coordinate of the center
    xFactor: "wobble" foctor in the x direction
    yFactor: "wobble" factor in the y direction
