// This basic one-dimensional 'fire' simulation works roughly as follows:
// There's a underlying array of 'heat' cells, that model the temperature
// at each point along the line. Every cycle through the simulation,
// four steps are performed:
// 1) All cells cool down a little bit, losing heat to the air
// 2) The heat from each cell drifts 'up' and diffuses a little
// 3) Sometimes randomly new 'sparks' of heat are added at the bottom
// 4) The heat from each cell is rendered as a color into the leds array
// The heat-to-color mapping uses a black-body radiation approximation.
//
// Temperature is in arbitrary units from 0 (cold black) to 255 (white hot).
//
// This simulation scales it self a bit depending on SEGLEN; it should look
// "OK" on anywhere from 20 to 100 LEDs without too much tweaking.
//
// I recommend running this simulation at anywhere from 30-100 frames per second,
// meaning an interframe delay of about 10-35 milliseconds.
//
// Looks best on a high-density LED setup (60+ pixels/meter).
//
//
// There are two main parameters you can play with to control the look and
// feel of your fire: COOLING (used in step 1 above) (Speed = COOLING), and SPARKING (used
// in step 3 above) (Effect Intensity = Sparking).
