Support for DCAM on win64

Update to Image Acquisition Toolbox's DCAM adaptor to support win64.

This update to Image Acquisition Toolbox's DCAM adaptor should add support for 64-bit versions of Windows (XP, Vista, and 7). It requires the R2011b versions of MATLAB and Image Acquisition Toolbox, as well as version 6.4.6 of the CMU DCAM driver which is included in the zip file.

In order to use the updated adaptor, download the attached zip file and then execute the following commands from the MATLAB command prompt:

>> cd(matlabroot)
>> unzip(pathToZipFile)

After unzipping the zip file, install the CMU DCAM driver located in <MATLAB>\toolbox\imaq\imaqextern\drivers\<ARCH>\dcam where <MATLAB> is the directory that MATLAB is installed in and <ARCH> is win32 or win64. Finally, restart MATLAB and "dcam" should be listed as an installed adaptor by IMAQHWINFO.
