A simple counter that starts counting at 1 at the top of the page, and each time it is invoked, will increase its value by one.  
These counters are transient, and relative 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. The 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 have the value true or false, and determines if the counter value should be visible on the page, the default is true. This parameter is optional.

!Example

[[{Counter}], [[{Counter}], [[{Counter}], [[{Counter}], [[{Counter name='aa'}] 

produces

[{Counter}], [{Counter}], [{Counter}], [{Counter}], [{Counter name='aa'}]

The value of "counter" at the end is [{$counter}] and the value of "counter-aa" is [{$counter-aa}].

__This__
{{{
[{$counter}], [{$counter-aa}]
}}}

__produces this__\\
[{$counter}], [{$counter-aa}]
