PA 16.1: Refactor crud.js

Copy the ca13-solutions code from the course Dropbox folder Links to an external site. (or a newer version of that code) to a new folder in your Git repository: pas/pa16.1.

The file js/crud.js has a lot of redundant code. Refactor it so that there's only one function that makes a call to $.ajax(), and all the functions that currently make $.ajax() calls now call that function instead. You should aim to make other functions as short as possible (potentially 1 line of code!).

Here's the rubric:

[ ] a new function exists in js/crud.js and is the only one that makes a call to $.ajax()
[ ] all other functions in js/crud.js that used to make $.ajax() calls now call the new function
[ ] there is very little redundant code (if any) in js/crud.js
[ ] the code is well commented and styled
[ ] there is a header at the top of the file that includes the name of the author(s) and a brief description of the file
[ ] the PA folder includes a README.md file with the required information in it 

Submitting PAs

Be sure to create a README.md with the following information:

• who you worked with (say "I worked alone" if you didn't have a partner)
• how long you spent on the assignment
• the PA option (and, if applicable, the earlier PA option it builds off of)
• a copy of the PA option's rubric, filled out (only submit if you can honestly check off each of the criteria)
• what the most challenging aspects were
• any lingering questions you have about the assignment

Commit and push your git repository to GitHub, then paste a link to your PA directory.
