!!! Overview
__Counter__ is a [JSPWikiPlugin] which acts as a simple counter that starts counting at 1 at the top of the page, and each time it is invoked, will increase its value. These counters are transient, and relevant to the current page view only — i.e. two persons viewing the same page at the same time get their own counters.
The current counter value is accessible also as a [WikiVariable]. The name of the variable is "counter", or "counter-<name>", if you have defined a counter name.
! Parameters
* __name__ = ''counter name''. You may define as many counters per page as you want; you just need to separate them with the ''counter name''. This parameter is optional.
* __increment__ = ''value''. (Since 2.8) The amount to increment the counter with, it may be both a positive and a negative value, the default is 1. This parameter is optional.
* __start__ = ''value'' (Since 2.8) The starting value of the count, the default value = 0. This parameter is optional.
* __showResult__ = ''true/false'' (Since 2.8) Can be true or false, and determines if the counter value should be visible on the page, the default is true. This parameter is optional.
