What is Northing and Easting?

Our engineers often find it handy to know how far North/South and East/West one has traveled from a starting position.  All one needs to do is subtract off your current position and then calculate the relative North and East change.  The HGDR has a plotting report which does this for you and even produces a CSV file of data.
