Looking for voting district projection info
Beginning of file to plot and analyze the different council districts.
Made a google doc of the districts from the charter text, then exported as csv and have that here.  Now am reading it into ipython, next read the census and put all the census features with matching tracts into a new data structure.
Untest but may have all the right census blocks in a good data structure for plotting
Have a bunch of tracts plotted, but there are a bunch of non-Seattle ones in there- is there a key collision producing that?
