/*
* Main class with start method for initializing and controlling the program
* Algorithm/Pseudocode:
* 1. Declare certain variables, including the BorderPane, RightPane, ObservableList of Filings, CaseData,
*    and the weekly filings query for the scope of the entire class to be used in multiple class methods
* 2. Within the start method, instantiate CaseData, which contains the necessary methods to return the data for filings
*    to populate the ObservableList of items
* 3. Load in and format icons via an ImageView array for use as buttons in the program
* 4. Instantiate buttons (and format them) for this program and give each a graphic from the ImageView array,
*    including a refresh button.
* 5. Instantiate, format, and add buttons to LeftPane (except the refresh button), which will be 100 pixels wide
* 6. Before instantiating RightPane, invoke getFilings within caseData with the proper parameters to load the weekly
*    filings into an ArrayList which in turn is passed to the observable list.
*       a. This step will take a while as the program waits on the URL to load, then parses that JSON data
* 7. With the JSON data now loaded into the observable array list, this list (items) is passed when instantiating
*    RightPane, which uses the list to feed the cell factory and generate each cell
*       a. For each JSON object it loads data from unique cases, this is necessary for links to cases
*          (this is an inefficiency I didn't have time to fix, as it makes so many requests and parses
*          so many objects it takes a long time to load)
* 8. Create a text header using HBox, this will be at the top of the RightPane
*       a. Within this HBox also place the refresh button, along with a Region for spacing
*       b. The Region needs to be HGrow = Always so that the header and the button stay in opposite ends of the box
* 9. Add RightPane and header to a VBox, with VGrow for the ListView as Always, to avoid height gaps
* 10. Create a BorderPane, set the left as the LeftPane, and set the right as the VBox containing the header
*     and list view
* 11. Add BorderPane to Scene and the Scene to a Stage, then show stage.
* 12. Add event handling methods to buttons to change between weekly filings and search results (also to refresh)
*       a. Button1 handles event by setting BorderPane right to hold the ListView with weekly filings
*       b. Button2 handles event by setting BorderPane right to hold a search TextField
*         i. When the user presses enter, the words in the TextField are split into an array
*         ii. Each term is inserted into a standard query, which makes up the URL
*         iii. getFilings is invoked to get filings based on the query
*         iv. The filings are added to a ListView (RightPane), which is added a VBox with the search TextField
*       c. Refresh button handles event by switching out the items in the list view with newly queried results
