     1= defNodes: Define Nodes used in Experiment =
     2
     3This command defines a set of nodes used in the experiment. An experiment can contain multiple such declarations.
     4
     5== Syntax: defNodes(setName, selector, &block) ==
     6
     7  * '''setName:''' Name of the defined set.
     8  * '''selector:''' Selects the nodes contained in this set.
     9  * '''block:''' Instructions for all nodes in the set.
     10
     11The 'setName' is a simple string which is used in the remander of the experiment script to refer to this set of nodes.
     12
     13The 'selector' defines which nodes are in the set. A selector can have the following forms:
     14
     15  * [x,y]: Describes a single node at location x@y
     16  * [x1..x2, y]: Describes a set of nodes along a line starting at x1@y and ending at x2@y. For instance, [2..4, 5] defines the nodes [2,5], [3,5], [4,5].
     17  * [x, y1..y2]: Same as previous, but for the y coordinate.
     18  * [x1..x2, y1..y2]: This defines a rectangle area of nodes within the grid.
     19  * [[x1,y1], [x2,y2], [x3,y3]]: An arbitrary long list of single nodes. Obvioulsy, any entry in this list can also use the line and rectangle descriptions defined above.
