constructor

Parameters:

histRootModel - The root node of a Xholon subtree in the model, that will be traversed looking for instances of the xholon class.

histRootView - Root node in the view. This is the "HistogramViewer" node.

xhClass - A Xholon class whose instances will be queried for values, using getVal().

numBins - Number of bins.

nameConcatLevels - Number of composite levels to concatenate in deriving name.
