LAB #3: Spatial queries and joins
  (1) Main Idea: Compare Cambridge housing prices with the 
      socio-economics of the neighborhood and proximity 
	  to Mass Ave
  (2) Add new columns to data tables
  (3) Merging, editing, saving data (e.g., to compute
      the percent with high school education)
  (4) Spatial joins to find neighborhood containing each sale
  (5) Buffering Mass Ave and comparing sales prices of 
      housing that is close/far
  (6) Extracting Mass Ave street segments with a specific coordinate system
  (7) File locations and ArcMap startup: 
  -- Checking ArcMap's 'scratchspace' location to avoid performance problems
  -- You can start this week's lab with the same 11.188_lab2_web.mxd document
     and shapefiles as were bundled into the zipped cambridge_shapefiles for 
     last week's lab.  That way, you will have the MassGIS and ESRI web 
     services and you can add the additional shapefile (middle_county.shp) 
     after copying it to c:\temp.
