# example usage: python split.py example.csv 200
# above command would split the `example.csv` into smaller CSV files of 200 rows each (with header included)
# if example.csv has 401 rows for instance, this creates 3 files in same directory:
#   - `example_1.csv` (row 1 - 200)
#   - `example_2.csv` (row 201 - 400)
#   - `example_3.csv` (row 401)
