ExpSampler

Sampler in which sampling level ratios are distributed in an exponential way. More formally, each sampling level corresponds to a sample with 1.0 / pow(base, level) * 100% of the original size.

T: the type of the elements of the sequence
base: the base to use for calculating the ratios, as described above
