/**
|
|
* Initiates a counter that is incremented every time you call it
|
|
* <pre>
|
|
* * name : the counter name, define it if you want to have multiple concurrent counters
|
|
* * start : the start value, if it's set, it will reset the counter to this value, defaults to 1
|
|
* * skip : the value to add to the counter at each call, defaults to 1
|
|
* * direction : "up" (default) or "down" to define whether the counter increments or decrements
|
|
* * print : if false, the counter will not output the current count, defaults to true
|
|
* * assign : if set, the counter is saved into the given variable and does not output anything, overriding the print parameter
|
