    Within this package, you will be able to find a set of classes and functions
    that allow for additional functionality that can be used in the building blocks.

    This goes about file handing, mathematical helper functions, an implementation
    for a `heap`, a set of packaging classes as required for the
    :class:`pypdevsbbl.generic.transformers.Pack` and :class:`pypdevsbbl.generic.transformers.Unpack`
    blocks and a set of inverse cumulative distribution functions that can
    be used in the :class:`pypdevsbbl.generic.generators.RandomNumberGenerator`.

        Note:
            The graphical representation that will be created is not a valid
