FastLED Analog Strip Gradient Fade

//Main Goal: Analog Strip fades from one defined hue to a second defined hue
//Secondary Goal: 4 analog strips repeating this action with each delayed slightly. (2 Variables to define delay amount and overall speed fade occurs)

#include "FastLED.h"

// fast led constants
// #define DATA_PIN    3        // change to your data pin
// #define COLOR_ORDER GRB      // if colors are mismatched; change this
#define NUM_LEDS    1       // change to the number of LEDs in your strip

#define REDPIN   5
#define GREENPIN 6
#define BLUEPIN  3

// change WS2812B to match your type of LED, if different
// list of supported types is here:
// https://github.com/FastLED/FastLED/wiki/Overview
//#define LED_TYPE    WS2812B

// this creates an LED array to hold the values for each led in your strip
CRGB leds[NUM_LEDS];

// fill_gradient variables (except direction as I wasn't sure what variable type to make it?)

/*
  arguments are:
  array: the name of your "CRGB name[NUM_LEDS] definition above
  start_led: which index number (0 is first pixel) to start with?
  start_hue: CHSV form (hue, sat, bright) of color/brightness for start led
  end_led: which is the last pixel in the gradient?
  end_hue: CHSF form for color of last pixel in gradient
  direction: thinking of a 0-255 color wheel, which direction should the
    gradient ramp through? Change the below to SHORTEST_HUES and you'll
    see that it goes red to blue through violet. Compare that to this, which
    goes the "long way" through yellow, green, and cyan.
    directions explained here: http://fastled.io/docs/3.1/colorutils_8h_source.html
