@section{argument}
 repeats
number of segments.

@section{argument}
 len
length of each segment.

@section{argument}
 step
how far to step the start of each segment from previous. step can be negative.

@section{argument}
 start
what index to start at.

@section{argument}
 wrapAtEnd
if true (default), indexing wraps around if goes past beginning or end. If false, the pattern stops if it hits a nil element or goes outside the list bounds.
