+The included datasets are provided to enable the testing of Spatial Bloom 
+Filters implementations. The sets have been designed for a filter built as an 
+array of 1-byte values: because of this, the maximum number of areas is 255.
+
+The test datasets are based on 16,776,960 elements (255*65792) and 255 areas. A 
+single element-area allocation case is provided: a uniform distribution where 
+each area has 65,792 elements. This set is to be used in conjuction with the 
+16-bit datasets list of elements (elements.csv), as they are the same. 
+Similarly, the list of elements not in test dataset (non-elements.csv) for the 
+16-bit datasets can also be used for checking false positives in the 8-bit-large 
+sets. This counter-set contains 500,000 elements.

+			the first value is the area, the second (separated by a
+			comma) is the element
+
+For each of the files above, a '-count' CSV file is also included. The file 
+lists the number of elements for each area.
