Create Parallel List Variables

Term with matching definitions, in separate but parallel lists, are:

• Sequence: a set of instructions or statements executed in order, usually from top to bottom
• Iteration: a structure that repeats one or more instructions: loop
• Selection: a conditional instruction that lets the program branch between two or more alternatives: if-then-else

Requirements

1. Pick a theme/class, i.e. biology or calculus, and create a vocab notecard app with at least 9 terms.
2. Must have a better UI than TClark's
3. Add one enhancement besides just pretty UI: think of how you study vocabulary and add features from notecards to your app
   • Good ideas done in the past:
     • Allow users to add their own terms (be careful, they should only be able to add terms if the textboxes are not empty)
     • Add a countdown timer that will display the definition after 10 seconds or so
     • Show users the definition, and have them enter the term, and display whether they got it right or wrong
     • Make a hint button that will display a picture representing the term, then hiding the picture for next next
     • Slider to change the font size or index
     • Translate the terms
     • Use text-to-speech and have it "speak" the term and the definition.
     • Use an image component instead of LabelTerm to display a dynamic math formula picture using the Google Chart API
       • Quadratic Formula: "https://chart.googleapis.com/chart?cht=tx&chl=x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}"
       • Integral: "https://chart.googleapis.com/chart?cht=tx&chl=\int%20e^x\,\mathrm{d}x=e^x%2bC"
       • Distance: "https://chart.googleapis.com/chart?cht=tx&chl=d=%5Csqrt%7B(x_2-x_1)%5E2%2b(y_2-y_1)%5E2%2b(z_2-z_1)%5E2%7D"
