    Fix bug in DenseInstance toString method and in TextGenerator class

    - Fixed bug in DenseInstance class toString method which resulted in always 
writing an arff file with class equal to zero.
    
    - Change TextGenerator class to create SparseInstances instead of  
DenseInstances.
    
    - Change the Attribute class in order to write the values of the nominal 
attributes between brackets in the attribute section of the arff file.
    
    - Change SingleLabelInstance classAttribute method in to return the correct 
attribute that represents the class value.
    
    - Override toString in SparseInstance class in order to write sparse 
formatted arff files.
