## Internal: generates neighborhood list for diploid loci

### Description

This is for use in `alleleinit`. Given a neighborhood list of individuals, a new neighborhood list is generated in which there are two entries for each individual (entry 1 and 2 refer to individual one, 3 and 4 to individual 2 and so on). Neighborhoods are preserved and additionally the two entries belonging to the same individual are marked as neighbors.

### Usage

      build.ext.nblist(neighbors,n.individuals=length(neighbors))

### Arguments

`neighbors` | list of integer vectors, where each vector contains the neighbors of an individual.
`n.individuals` | integer. Number of individuals.

### Value

list with `2*n.inidividuals` vectors of integers as described above.
