Process the command line arguments to know which GPIO
to set and what to set it to. Then create the GPIO
object and call the appropriate functions on it.

This class is used for accessing a GPIO via the
/dev/gpiochipX interface.
It requests a GPIO line handle from the GPIO device to
do the actual operation on.
The GPIO number to use, for AST chips at least, is the
actual GPIO number, such as GPIOA0 = 0 and GPIOA7 = 7.
The class currently only supports writes.

This application can write GPIOs. Read support may
be added in the future.
Aside from just setting a GPIO low or high, it can
also do: 0 -> <delay> -> 1 or 1 -> <delay> -> 0.
All functionality will be added in future commits
