Crashes when there is no variance

[tkortekaas]

Given input:

final RunParameters runParameters = new RunParameters("path/to/dataset.csv", SimEnum.PEARSON_CORRELATION, 1, 1);
runParameters.setTopK(1);
runParameters.setQueryType(QueryTypeEnum.TOPK);

final CorrelationDetective correlationDetective = new CorrelationDetective(runParameters);
queries.ResultSet res = correlationDetective.run();

and dataset.csv

,A,B,C  
x,1,5,4  
y,2,6,4  
z,3,7,4  
w,4,8,4

an ArrayIndexOutOfBoundsException occurs. This happens, independently of the value of skipVar.
