Enumeration of different approaches towards the interval and color scales in case of HeatMap layer.
Continuous - The distribution of the colors in the color scale is even based on the measure. This is good for the
data sets with even distribution.
Quantiles - The distribution of the colors in the color scale is uneven based on the value. It is distributed evenly
based on the measure for the lowest 10%, 10% to 20% and so on. Basically it categorizes measures based on to which
quantile the measure belongs. This is good for data sets with uneven distribution.
