+ * This program generates datasets for Rodinia's kmeans

+ * Usage:
+ * datagen <numObjects> [ <numFeatures> ] [-f]
+ *
+ * numFeatures defaults to 34
+ * Features are integers from 0 to 255 by default
+ * With -f, features are floats from 0.0 to 1.0
+ * Output file is "<numObjects>_<numFeatures>.txt"
+ * One object per line. The first number in each line is an object ID and is
+ * ignored by kmeans.
