Create Button Component that conforms to Styleguide.

[kevinreiss]

Current display

Buttons have only basic styles at the moment.

Desired display

Buttons should conform to the WDS Styleguide.

Acceptance criteria

• Buttons should take on the styles described in the styleguide.
• I can successfully use this feature with Voice Over in Safari.
• I have checked this feature using one of the following browser extensions and confirmed that it does not add any level A or level AA issues:
  • axe dev tools
  • Lighthouse
  • Wave

Notes

We will need to add the ability to pass a function into the component that is called when the button is pressed.

We discussed this at the stand-up on 2/5 and decided that this was not a MVP ticket for the updated UI, it's a re-factoring ticket.
