The server listens on '/' for GET queries with a url query format like
?l=*&r0=*&g0=*&b0=*&a0=*&t0=* ... &rl=*&gl=*&bl=*&al=*&tl=*

Where l is the number of points on a gradient. And each point of the gradient has a r* g* b* a* and t* where * is the index.

r g and b are the red green and blue 8-bit colour components of a point on the gradient. A is the 5-bit global component of the led at that point.
t is the offset from the start measured in leds.

Each point also has an optional &m 'movement' argument. &m should be either -1, +1 or 0 and represents the movement per frame or the point.
When no movement is set, 0 (no movement) is implied.

When movement is set, a &e 'edge' component can also be set for that point. &e defines what the point will do once it reaches an end of the strip.
Edge should be one of
w to wrap to the opposite end of the strip.
r to reverse direction
s to stop

If no &e is specified, s is implied.

A point on the gradient may have a movement &m and edge &e parameter, and has to have a &r, &g, &b, &a, and &t.
The whole gradient may have a duration &d parameter and must have a length &l
