wrote download-xml-forecast.scm: download current xml forecast for SLC from noaa site,
and save it to a file named according to current date.

So far I have written code to read an xml file and parse data into 
an internal forecast data structure.  The next task is to write a brief
program to download a 7-day xml forecast each evening (say, at 11 pm).  

Since observations are not available in xml format, I plan to use the 
next-day forecast as my observation.

Finally, I will build upon read-xml-forecast.scm to read a series of saved
xml forecasts, and output accuracy tables for the entire dataset.  
The function will be something like the following:

(measure-forecast-accuracy start-date end-date forecast-directory)

which will output a table:

StartDate-EndDate

2-day accuracy:
      avg. (minTemp / minTemp0)
      avg. (maxTemp / maxTemp0)
      ...
3-day accuracy:
      ...
7-day accuracy:
      ...


where minTemp0, etc are taken from the 1-day forecast.
