gear-inches: calculate the gear inches available for a given set of chainring

and cogs.

Implemented as two programs:

gi:

    Usage: gi wheel-diameter tire-size chainrings cogs

    (chainrings are a comma-separated list of chainrings, ie: 48,28)

    (cogs are a comma-separated list of cogs, ie: 12,14,16,19,21,26)

    If called as 'webgi', if generates the output as a html table,

    otherwise it's an ascii table.

gcalc:

    Usage http://..../gcalc.cgi

    On the first call, it spits out a html form so you can fill in the

    wheel size, etc;  submitting that form calls it again, and it gives

    you that html form (populated) + a chart of gear inches.
