Description of Datasets
-----------------------
The two datasets (dataset1 and dataset2) contain points in 2 dimensions.
Each line stores a point with the format: x,y

Example:

0.8453876286,0.2663324064
0.0514091278,0.6276424066
0.9667152615,0.6543817478
0.1644701151,0.3775747771



Description of Queries
-----------------------
The two files, Squeries and Uqueries contain rectangular queries in 2d.
They are given in the following format: x1,y1,x2,y2
One query in each line.

For example:

0.39131500000000002, 0.388181, 0.48027002966179061, 0.44183152828565975


In this query, the range in the x-dimension is [0.39131500000000002, 0.48027002966179061] and the range in the y-dimension is [0.388181, 0.44183152828565975]
