     function oreDetect()
             --[[ This function is a WIP system for the turtle to detect ores when it
             is mining and dig out the entire vein.  It will do so by comparing items
             around it to specific slots in its inventory which will contain common
             blocks such as smooth stone, gravel, dirt, etc.
             If one of these ores is identified, then the turtle will dig out the block
             and then move into the space that the block occupied and 'sense' the blocks
             around it again to try and find the continuation of the vein.
             Once the turtle has finished identifying the vein, it will return to it's
             initial position.  This last task may either be completed by recording
             movement as the turtle moves or by using a GPS wireless system and a
             basic 'goto' function for the initial coordinates.
