    Script to set up a Python test environment.
    
    I'm tired of pasting that PYTHONPATH environment setting out of the
    cheatsheet comment in setup.py, so I've set up a script that should
    work it out automatically (and, bonus, adapt to whatever host
    architecture I'm doing it on).

    Add a 'minimum power' option to powbegin.py.
    
    Apparently this totally pointless program is just so much fun to
    tinker with that I just can't stop once I get started :-) The new
    option allows me to ask for the smallest power of a _at least m_ that
    begins with the digits of b. So, for example, having found that the
    smallest power of 7 beginning "49" is of course 7^2, I can then add
    -m3 to the command line to ask 'OK, what's the _next_ one?' and be
    told that it doesn't happen again until 7^73.
    
    In particular, I've arranged for the _default_ minpower to be chosen
    in such a way that the program will never put the digits you cared
    about below the decimal point - e.g. asking for a power of 2 that
    begins "10" now returns 2^10 = 1024, which is more likely to be what
    you actually meant than returning 2^0 = 1.0 on a technicality. (And if
    you really did want the latter behaviour, you can say -m0 explicitly.)
