Description: Provides functions to work with directed (asymmetric) and 
    undirected (symmetric) spatial networks. It makes the creation of 
    connectivity matrices easier, i.e. a binary matrix of dimension n x n, where 
    n is the number of nodes (sampling units) indicating the presence (1) or  
    the absence (0) of an edge (link) between pairs of nodes. Different network
    objects can be produced by 'chessboard': node list, neighbor list, edge 
    list, connectivity matrix. It can also produce objects that will be used 
    later in Moran's Eigenvector Maps (Dray et al. (2006) <doi:10.1016/j.ecolmodel.2006.02.015>)
    and Asymetric Eigenvector Maps (Blanchet et al. (2008) <doi:10.1016/j.ecolmodel.2008.04.001>),
