4.  trait DlogGroup[ElemType <: ECPoint] extends AnyRef

   This is the general interface for the discrete logarithm prime-order group.

   This is the general interface for the discrete logarithm prime-order group. Every class in the DlogGroup family implements this interface.

   The discrete logarithm problem is as follows: given a generator g of a finite group G and a random element h in G, find the (unique) integer x such that g^x = h.

   In cryptography, we are interested in groups for which the discrete logarithm problem (Dlog for short) is assumed to be hard. The most known groups of that kind are some Elliptic curve groups.
