 When I use `PCA::Apply(arma::mat& data, const int newDimension)`, I get
 the following:

 :[ ryan @ greenstreet ]: $ bin/pca --input_file test_data_3_1000.csv
 --output_file pca.csv

 error: Mat::shed_cols(): indices out of bounds or incorrectly used

 terminate called after throwing an instance of 'std::logic_error'

 and the error appears to be coming from the call to `shed_cols()` in
