Inglenook puzzle generator

A python script to generate start and end arrangements for the inglenook shunting puzzle. Arrangements of wagons can be generated for 3-2-2 or 5-3-3 puzzles.

For example:

$ python inglenook.py 533 HAA ZKV IEA MLA YMO clam rudd HTA
The target order is: ['ZKV', 'HAA', 'MLA', 'HTA', 'rudd']

The starting setup is:
Long siding:         ['rudd', 'HTA', 'ZKV', 'YMO', 'IEA']
First short siding:  ['clam', 'MLA']
