feature or bug print statements

[wilwet]

When starting the driver in def init the type of interface is always printed. It would be nicer if you could add an debug flag or something like that to suppress the printing.

`

Debug

    if self.use_ce:
        print("Use software chip enable")
    if self.use_bitbang:
        print("Use bitbang SPI")
    else:
        print("Use hardware SPI")

Sorry, I meant to commit this a long time ago... Please check the "develop" branch and see if this is what you would expect. Thanks!

There will be a minor release soon, which includes this.
