[edit | edit source]##This code must be run in a folder that contains:
## 1. ./bank (contains .tex files for all bank wikiquizzes)
## 2. ./bank/images (images contain all the image files.
## 3. ./input/xxx.csv (where one or more csv files are situated)
## 4. ./output (where the four xxx.tex files will be created)
## 5. ./output/images (I currently requre to copies of the images)
##The extra images file (in output) is not required for this program to run,
## but is required to run the output xxx.tex files that are created. Also
## created in the output file is an empty ./output/xxx directory where
## the pdf files created by LaTex can be placed (I use Miktex)
##
##Also in the directory that holds this program (program.py) is another
## program called template.py. Use template.py to create the xxx.csv files
## used to create the xxx.csv files used by program.py.

##This code opens a testfile (e.g. anyTest.csv) and
##verifies that it is properly formatted. It checks that:
##1. The testName is in the 01 cell of the csv file
##2. The number of questions in the bank in the 00 file is correct
##3. Each available question has a top row integral question number
## If possible it fixes the error and creates anyTestUPGRADE.csv
####Code requires ./bank/ and ./input/template/ directories
## getInfo returns testName
## getCheckData returns csvData (what might be on test)
