+CODE = ARITHENCO(SEQ, COUNT) encodes the given sequence (SEQ) using arithmetic coding.
+COUNT is vector whihc gives information about the source statistics (i.e. frequency of each symbol in the source alphabet)
+CODE is the binary arithmetic code
+Source Alphabet is assumed to be {1,2,....N} where N is a positive integer
+Therefore, sequence should be finite and positive
+Length of the COUNT should match the length of the source alphabet
