Description
The example demonstrates usage of NumberBucket process. The NumberBucket will create a number of buckets with same size to put number into. A bucket is defined as "{from} - {to}" format, for example: "0-20", "20-40".
The NumberBucket takes the "step" a must-have property. This is actually the size of a bucket. Beside the "step", there are several optional settings such as "prefix", "suffix", "thousandSeparator", "decimals" and "decimalPoint". Those are actually the settings to format number.
