Description
A report function that counts groups in a report. If a null-group name is given, all groups are counted.
The group to be counted is defined using the property "group". An optional container group can be defined using the property "parent-group". When the group start event of that group is encountered, the counter will be reset to '0'. If the group property is not set, all group starts get counted.

<property name="group">ORDER NUMBER GROUP</property>
<property name="parentGroup">CUSTOMER GROUP</property>
