Baby Names
Using the baby names data from The day 3 challenges:
 * 1) Get the ratio of names that start with each letter.
 * 2) * Do this for boys and girls.
 * 3) * Hint First line of output should be something like:
 * a: boys: 0.1002914920750592 girls: 0.17587602795796703
 * 1) Are girls or boys more likely to have a name that is used by both genders?
 * 2) Figure out how to change the ssadata.py file so that it loads births from 2017 instead of 2018.

Above and beyond

 * 1) Figure out how to load two years of birth data simultaneously and compare them (e.g., identify the top 20 names from 2017 and figure out how many more/fewer people were named those names in 2018).
 * 2) Visualize some of the differences (probably in Excel)
