Random replacement policy.
Randomly-selected individuals in the destination population are replaced by randomly-selected incoming individuals. The number of individuals replaced is limited by the maximum incoming rate parameter.

Clone method.
Provided that the derived policy implements properly the copy constructor, virtually all implementations of this method will look like this:
return base_ptr(new derived_policy(*this));
@return migration::base_s_policy_ptr to a copy of this.

Assign pairs of individuals for replacement during migration.
Note, that this method does not alter the target population, it just provides the replacement choice. The actual replacement is done in the archipelago class. The first element of a pair should be the index of the one from the destination population. The second one - the index of the individual from the immigrants vector which is to replace the first one.
| [in] | immigrants | vector of incoming individuals. |
| [in] | destination | population into which the immigrants will be replaced. |
