Please make sure the program executes in hill. If not, please
include the compile-execution details in the Readme file. 
Also, please note that the README file, coding style and output
format also count towards your grade. 
Name your executable file project3
  


Things to be turned in:

README file should contain:
 -Explanation of the concepts behind the solution i.e 
  how the existing algorithm in section 7.7 is modified to 
  check if a given polygon is simple in 0(n log n) time.
 -Your assumptions about the input, input file format, output
  format, compilation and execution details of the source code.
 -Time complexity analysis of the algorithm used.
