# Write a function that reads a todo.csv file.
# The todo.csv file contains date, time, and activity
# formatted as, for example,
#    date,time,thingstodo
#    31oct,8am,eat
#    31oct,9am,relax
#    31oct,10am,meet advisor
#    31oct,11am,read
#    31oct,12pm,eat
#    31oct,1pm,get ready for cs1111
#    31oct,2pm,cs1111
#    31oct,3:30pm,some other class
#    31oct,5pm,do homework
#    31oct,6pm,eat
#    31oct,7pm,practice writing program
# where the first line is a header line

# The function then counts the numbers of activities that will happen
# in AM and PM, and return a dictionary containing the numbers of
# AM activities and PM activities.
# For example, {'number_AM_todo': 4, 'number_PM_todo': 7}
