Remove usage of CSV module from sqlmain.py

medict/managers/sqlmain.py

Line 16 in 93801ab

def parseCSV(fp): #Why can't you use CSVManager.list_od_from_csv for this?

For the sake of code cleanliness, it is better to have a single module handling all of the CSV related issues. sqlmain.py should not have any csv related code at all.

The function defined at:

medict/managers/sqlmain.py

Line 16 in 93801ab

def parseCSV(fp): #Why can't you use CSVManager.list_od_from_csv for this?

Is the same as the function defined at:

medict/managers/csvmanager.py

Line 128 in 93801ab

def list_od_from_csv(self,datafile=None):

There is absolutely no need to repeat code again and again.
