NicheModelLinks.

1	NicheModelLinks(n, S, C=0.15, niche.positions=NULL, probabilistic=FALSE)

`n`	the number of sets of links to generate.
`S`	the number of species in the pool.
`C`	the directed connectance (number of links / number of possible links) of each set of links.
`niche.positions`	a vector of ‘S’ numbers, givien species' positions on the niche axis, or `NULL`
`probabilistic`	if`TRUE`, the function uses the probabilistic niche model

Implements the Niche model of Williams and Martinez (2000) and the Probabilistic Niche model of Williams et al 2010

A list of ‘n’ matrices, each with approximately $S * S * C$ links.
