     a couple of the header files in Steinberg's ASIO SDK, and it'd be easy to copy
     about 30 lines of code into this cpp file to create a fully stand-alone ASIO
     implementation...
 
     ..unfortunately that would break Steinberg's license agreement for use of
     their SDK, so I'm not allowed to do this.
 
     This means that anyone who wants to use JUCE's ASIO abilities will have to:
 
     1) Agree to Steinberg's licensing terms and download the ASIO SDK
         (see http://www.steinberg.net/en/company/developers.html).
 
     2) Enable this code with a global definition #define JUCE_ASIO 1.
 
     3) Make sure that your header search path contains the iasiodrv.h file that
        comes with the SDK. (Only about a handful of the SDK header files are actually
        needed - so to simplify things, you could just copy these into your JUCE directory).
