The grouping of data pipes into a bundle.
bundle: The pipe bundle is a special grouping or clustering of data pipes.
pipe: The name of the data pipe to add to the bundle.
Data pipes can be grouped or clustered together through special structures known as pipe bundles. If the specified data pipe bundle does not currently exist, it will be created.
To add the data pipes `test 1', `test 2', and `test 3' to the bundle `first analysis', type the following:
[numbers=none] relax> pipe.bundle('first analysis 1', 'test 1')
[numbers=none] relax> pipe.bundle('first analysis 1', 'test 2')
[numbers=none] relax> pipe.bundle('first analysis 1', 'test 3')
