Bug #1

Description of the bug: NumberOfA,numberOfT,numberOfC,numberOfG in the method  countNucleotides is not referenced correctly.


Lines of source code that contain the bug: [86]   int numberOfA = 0;
		                           [87]   int numberOfT = 0;
	                                   [88]   int numberOfC = 0;
		                           [89]   int numberOfG = 0;


Lines of the fixed code:  this.numberOfA = 0;
		          this.numberOfT = 0;
	                  this.numberOfC = 0;
		          this.numberOfG = 0;
