API - Spoontacular - Meal Planner Integration

---

Description:

This issue details the Meal Planner integration within the app. It is in the MealActivity.kt and contains the Meal Planner Generation, Add Meal Plan classes, Clear Meal Plan Day class, and Delete Meal Plan Class.

I'm keeping this issue open just because I'm having an error with the Meal Generation button, it is not going to MealResult.kt

---

Steps To Reproduce:

1. Design the class around the corresponding xml
2. Update the retrofit interface so it has the correct http requests and parameters
3. Make the class, follow the guidelines in the Spoonacular documentation

---

Expected Vs. Actual Behavior:

Expected Behavior: Returns the data for a meal plan Actual Behavior: Returns ID data for meals and makes them global variables

Hey @IanTDuncan, since you're still working on this issue, I moved it to the April Milestone.
