Declaration of a Bimodal Interval Prediction replacement policy. Has a probability of when placing new entries, placing them as MRU.

Although both LRU and LIP can be seen as specific cases of BIP where the bimodal throtle parameter are 1 and 0, respectively, we decide not to inherit from it, and do the other way around (inherit from LRU) for efficiency reasons.

In the original paper they use btp = 1/32 ~= 3%.
