Detailed Description

A class for connecting several filters into one filter with logical "and" between them. For example: if the 2 filters are: "IPv4 address = x.x.x.x" + "TCP port dst = 80", then the new filter will be: "IPv4 address = x.x.x.x _AND_ TCP port dst = 80"
This class follows the composite design pattern
For deeper understanding of the filter concept please refer to PcapFilter.h

add some methods: "addFilter", "removeFilter", "clearAllFilter"
