import wk data returns list of unique weeks

ORgenerator.py
- import_dwk function returns list of unique weeks in dataset; improved from entering an empty list as an argument into the function

odds_c_a_6wk_v7-8-13.py
- changed code to reflect difference in import_dwk function for OR by peak weeks chart
OR by all weeks chart

OR_allweeks.sql
- export data that will allow you to calculate an odds ratio for all weeks in the dataset from SDI database

OR_allweeks.py
- using SQL_export data, draw OR by week chart where there is a different line per season
- during summer months, OR generally falls between the range of 3 and 4. Perhaps we can consider those values to be the "baseline"
OR_allwks: season 1 data shifted to wk53 of chart

OR_allweeks.py
- season 1 data begins on wk53, not wk40
because those data are missing
- shifted x-axis of season 1 data to
reflect that missing data
seasonseverity ORgenerator updated

OR_seasonseverity.py
- main script imports ORgenerator instead of
ORgenerator_v070813
- changed assignment of od module functions to
dictionaries and adjusted arguments to reflect
changes in ORgenerator.py
- this produces cleaner code because the
ORgenerator_v070813 functions did not return
dicts. Instead, they used empty dicts as args
and the filled dict was effectively left in the
main code.
return vals from fxns, lat/long fxns

ORgenerator.py
- change functions return dictionaries and lists
- add import_z3_ll to generate dict with z3 = (lat, long)
- add import_z3_OR_season to generate dict with
(seasonnum, zip3) = OR
OR vs lat/long first commit

OR_latlong.py
- scatter plot of OR vs latitude, different
color per season
- scatter plot of OR vs longitude, different
color per season
added comment about script function

OR_latlong.py
- added comment about script function
OR maps show continental US only

map-zipcodes_ECLedit.R
- for OR map per season and log(OR) map per
season, removed zip3s that corresponded to
areas in Alaska and Hawaii and redrew maps
that showed only continental US
- this was to decrease the amount of white-
space shown on the maps
OR map per season where attack rate is bubble size

map-zipcodes_ECLedit.R
- add OR map by season where attack rate per 1000
instead of population size is the bubble size on
the map
