+### Examples:
+make ARG="in=../../../lib/dictBuilder in=../../../lib/compress"

+###Benchmarking Result:
+- First Cover is optimize cover, second Cover uses optimized d and k from first one.
+- For every f value of fastCover, the first one is optimize fastCover and the second one uses optimized d and k from first one. This is run for accel values from 1 to 10.
