Graph layout by multidimensional scaling

layout_with_mds uses metric multidimensional scaling for generating the
coordinates. Multidimensional scaling aims to place points from a higher
dimensional space in a (typically) 2 dimensional plane, so that the distance
between the points are kept as much as this is possible.
By default igraph uses the shortest path matrix as the distances between the
nodes, but the user can override this via the dist argument.
This function generates the layout separately for each graph component and
then merges them via merge_coords.
A numeric matrix with dim columns.
