filters class is the container for a list of filter objects.
The class mainly exists for displaying multiple filters/gates on one single panel(flowFrame) of xyplot.
Note that it is different from filerList class which is to be applied to a flowSet.
In other words, filter objects of a fliterList are to be applied to different flowFrames.
However,all of filter objects of a filters are for one single flowFrame, more specifically for one pair of projections(parameters).So these filters should
share the common parameters. And filtersList is a list of filters objects,which are to be applied to a flowSet.
