main.c :
--------------------------------------------------------------------------------------------------------------------------------

conatins the actual logic.
genSortedRuns() 
	- creates sorted runs from the input file
	- writes them into "currentDIR"/SortedRuns

mergeSortedRuns() 
	- merges the runs generated from previous step
	- continues till entire file is sorted 
	- writes to the output File specified


Execution :(with example)	
-------------------------
cc main.c
./a.out

Enter the name of file to be sorted : /home/revanth/Desktop/final/test.bin       
Enter the name of output file : /home/revanth/Desktop/final/test-out.bin
Enter the number of attributes to be soted on : 2
Enter the attributes to be soted on : 
8
-2
Enter the bufferSize in Bytes : 90112


**** PLEASE DELETE THE DIRECTORY "./SortedRuns" BEFORE TESTING OTHER TESTCASE***********

--------------------------------------------------------------------------------------------------------------------------------
readIntBin.c :
--------------------------------------------------------------------------------------------------------------------------------
can be used to read the bin files (specifically output)

Execution :(with example)
-------------------------
cc readIntBin.c
./a.out

Enter no. file path to read : /home/revanth/Desktop/final/test-out.bin
Enter no. rows to read : 120001
