Allow users to generate a sample style or palette from the command prompt.

[tylertownsend]

Currently the command prompt only allows users to generate themes. The options for generating the theme are:

1. Use an existing color-palette and/or style in combination with sample color-palette and/or style.
2. Modify the imported sample color-palette and/or style and regenerate the theme.

• A user should have an option to get the sample color-palette or style from the prompt without creating a theme first.
