Ilysa by Example: Context Reference

This example documents all the possible options for the methods that create Chroma events. For Chroma specific details on what the options do, please refer to https://github.com/Aeroluna/Chroma.	package main

`SeqT` is the current time in the current sequence, on a 0-1 scale. As a special case, SeqT is 1 if the current sequence has only 1 step.	ctx.SeqT()
`SeqOrdinal` is the ordinal number of the current iteration of the current sequence, starting from 0.	ctx.SeqOrdinal()
`SeqLen` is the number of steps in the current sequence.	ctx.SeqLen()
`SeqNextB` is the beat number of the next step in the current sequence.	ctx.SeqNextB()
`SeqNextBOffset` is the difference in beats between the current step and the next step. As a special case, `SeqNextBOffset` returns the difference between the last beat and the ghost beat, if this is the last step.	ctx.SeqNextBOffset()
`SeqPrevB` is the beat number of the previous step in the current sequence.	ctx.SeqPrevB()
`SeqPrevBOffset` is the difference in beats between the current step and the previous step.	ctx.SeqPrevBOffset()
`SeqFirst` is true if this is the first step in the current sequence.	ctx.SeqFirst()
`SeqLast` is true if this is the last step in the current sequence.	ctx.SeqLast()
	ctx.Range(timer.Rng(0, 0.5, 6, ease.Linear), func(ctx context.Context) {
`B` is the current beat.	ctx.B()
`T` is the current time in the current range (or sequence), on a 0-1 scale. As a special case, `T` is 1 if the current range only has 1 step.	ctx.T()
`Ordinal` is the ordinal number of the current step in the current range (or sequence), starting from 0.	ctx.Ordinal()
`StartB` is the starting beat of the current range.	ctx.StartB()
`EndB` is the ending beat of the current range.	ctx.EndB()
`Duration` is the duration of the current range.	ctx.Duration()
`First` is true if this is the first step in the current range.	ctx.First()
`Last` is true if this is the last step in the current range.	ctx.Last()
	ctx.Light(l, func(ctx context.LightContext) {
`LightIDT` is the position of the current light ID for the current light, on a 0-1 scale.	ctx.LightIDT()
`LightIDOrdinal` is the ordinal number of current light ID.	ctx.LightIDOrdinal()
`LightIDLen` is the number of light IDs the current light has.	ctx.LightIDLen()
`LightIDCur` is the current light ID (effectively, `LightIDOrdinal` + 1).	ctx.LightIDCur()
	}) }) }) p.Dump() }
