/**
* Cycles between several values and returns one of them on each call
* <pre>
* * name : the cycler name, specify if you need to have multiple concurrent cycles running
* * values : an array of values or a string of values delimited by $delimiter
* * print : if false, the pointer will go to the next one but not print anything
* * advance : if false, the pointer will not advance to the next value
* * delimiter : the delimiter used to split values if they are provided as a string
* * assign : if set, the value is saved in that variable instead of being output
* * reset : if true, the pointer is reset to the first value
* </pre>
