gtMethod-class: A class to represent a gating method.
In openCyto: Hierarchical Gating Pipeline for flow cytometry data

A gating method object contains the specifics for generating the gates.

name: a character specifying the name of the gating method
dims: a character vector specifying the dimensions (channels or markers) of the gate
args: a list specifying the arguments passed to gating function
groupBy: a character or integer specifying how to group the data. If character, group the data by the study variables (columns in pData). If integer, group the data by every N samples.
collapse: a logical specifying wether to collapse the data within group before gating. it is only valid when groupBy is specified
