FIXME
DESCRIPTION
Class that implements the count operator. This operator counts the number of DLF records in the current group.
If the fields attribute is set, the count statistics will be equals to the number of different values present in the fields specified by that attribute.
Its also possible to express the count as a ratio of the total count for the group or table.
METHODS

fields( [$new_fields] )
Returns the fields for which we are counting the different values. This a reference to an array of DLF field names.
If the CW$new_fields parameter is set, it will be used as the new CW$fields value. It must be an array reference and should only contains valid field names for the current report specification's schema.
ratio([$new_ratio])
Returns how the count will be expressed. This can one of three possible values:
- none
- Default. The absolute count will be used.
- group
- The count will be expressed as a percentage of the group's count.
- table
- The count will be expressed as a percentage of the table's total count.
