The Contour class takes a function f and diplays color-coded values for f(x, y) over a two dimensional grid defined the lower (lb) and upper (ub) bounds.
The Histogram class takes a vector of values, counts the number of values in each of several intervals and displays the counts vertically in a histogram.
The Plot class takes x and y vectors of data values and plots the (x, y) data points.
The PlotM class takes an x vector and a y matrix of data values and plots the (x, y_i) data points for each row y_i of the matrix.
