Changes for the next version(s)

[micahcochran]

• Updated for scrape-schema-recipe library version 1.0.0, when released.
• recipeInstruction from recipe-scrapers library drivers (myplate.gov and NIHHealthyEating) should be a list type instead of a string.
• Use a priority queue for list of websites. This will require converting the scores (highest number for most important) to priority (lowest number most important). Put SiteMaps support in here as a mid-priority site. This will replace the high low URL lists. (This is a bigger change than the other two and should happen after.)
  EDIT:Scrap the priority queue issue. There really isn't any reason to do that because there are only two classifications. A priority queue wouldn't really simplify the code as is.
