> Create interface for weighing/sizing vertices

>                 Key: GIRAPH-260

>             Project: Giraph

> Different applications need to 'weight' vertices differently.  This is 
> important for determing when to move vertices across workers, how to 
> partition them, etc.  For instance, one application may wish to base these 
> decisions on the degree of each vertex, while another may want to also 
> include the weights of the edges.  Or, there may be a graph with heavy weight 
> values and few edges in general.  It would be good to have an interface 
> Giraph can use to compare and weigh vertices.
> Something like:
> {noformat}
> interface VertexWeigher<{the usual type silliness}> implements 
> Comparator<{more type silliness}> {
>    def compare()
>    def getWeight()
> }
> {noformat}
> But, of course, with a better name.  The default implementation could be 
> based on the vertex degree.  This would be a user-specified class, with a few 
> pre-provided options.
