/**
 * \file tsk_is_image_supported.cpp
 * Class to test whether a given image can be processed by tsk
 * 
 * Usage:
 *  Create a TskIsImageSupported object
 *  Call openImage
 *  Call findFilesInImg
 *  Call isImageSupported - if this returns true then the image is supported. If false or
 *                            if there was an error along the way, the image is not supported
