Some intial simplified components + stories

[infiniteluke]

• Adding a couple basic components just to get started.
• Added Storybook so that @tsmith512 can start working on styles without the rest of the components built. To test this:
  • Pull this branch
  • npm i
  • npm run storybook
  • Edit the color in src/components/Card/Card.scss
  • See update
