Add setters for replacing the default Edge and Node classes
...
This can be handy if the user wants to extend the functionality of those
classes. They can simply be inherited in a new class with that new class
being used in the Graph then.

Add Edge and Node classes to init.lua
...
This way they can be required separately from the Graph class.

Remove name attribute in Node class
...
Seems kind of redundant to have both an id and a name attribute.

Add anchor nodes
...
Nodes set as anchors won't be affected by the force directed layout.
They can be used to fixate the graph to a certain area.

Extend graph constructor to handle node tables
...
The nodes can either be a sequence of strings or a sequence of tables
containing id, name, x and y values.

This parameter can be accessed via the getName getter. If no value is
passed to the constructor the name variable will default to the id.

Add function for creating a "global" attraction point
...
This point won't show up in the graph itself and can not be interacted
with. Instead it only has the purpose to attract all nodes in the graph.
This can be useful if you have unconnected nodes and want to prevent
them from floating away.

Remove code for drawing the graph
...
Instead the draw function now takes a parameter of type function to
which it passes the edges and nodes tables. This means the user can (and
has to) handle the drawing of the graph.

Improve function to create a new graph based on data
...
The random function is now seeded properly and uses the x, y, w, and h
parameters passed to the function to determine in what range to randomly
place the nodes.

well.

This is the case if both the origin and the target of the edge point to
the same node or if an edge already exists between two nodes.
