## Convert CAR structural parameters to adjacency, weights, num format

### Description

This will convert alternate representations of CAR process structure into (adj, weights, num) form required by `dcar_normal`.

### Usage

    as.carAdjacency(...)

### Arguments

`...` | Either: a symmetric matrix of unnormalized weights, or two lists specifying adjacency indices and the corresponding unnormalized weights.

### Details

Two alternate representations are handled:

A single matrix argument will be interpreted as a matrix of symmetric unnormalized weights;

Two lists will be interpreted as (the first) a list of numeric vectors specifying the adjacency (neighboring) indices of each CAR process component, and (the second) a list of numeric vectors giving the unnormalized weights for each of these neighboring relationships.
