Builds an hexagonal grid over a spatial object using a convex hull.

1	hexgrid(x,width=NULL,n=NULL,buffer=NULL,convex=TRUE,seed=1)

`x`	A spatial object, ideally projected.
`width`	Approximate width of hexagonal cell
`n`	Number of divisions to approximately split the convex hull along the x direction.
`buffer`	Width of a buffer around the convex hull of `x` to extend the grid
`convex`	Keep cells over convex hull or over `x` objects?
`seed`	A seed to obtain the same grid since it is based on `spsample`.

When x is not projected, it is projected using laea and centered on mean x and y values and given back with the initial CRS. Better to input projected data anyway for displaying...

A SpatialPolygonsDataFrame hexagonal grid overlapping x.
