Modify image loading to load the associated csv file

[apsexton]

The data folder contains sample images and associated .csv files.

• When an image is loaded, try to read the associated .csv file (giving suitable error dialogs if the file doesn't exist).
• Make a class called Component in Layout.Model to hold the contents of a single line of the csv file. For the moment, we are only interested in the bounding box information (the x, y, w and h columns) and the columns in the csv file may change later in the project anyway so ignore the other columns
• Have the class have a Rectangle class variable initialised to these values.
• Add an ArrayList of Component objects to the Model.
• On reading the .csv file, add all the resulting Component objects to the model (after clearing any previous Components from the ArrayList)
• Modify the canvas display to draw all the rectangles in the list of components in some suitable stand out colour.

Should I change the loadImage method in Controller (and create a separate loadCSV method in Model) or in Model to implement the .csv file readings?

[apsexton]

To keep things simple initially, I suggest the former, i.e. change the loadImage method in Controller and create a separate loadCSV method in Model.

Later on we may refactor the code to make a csvFile class in the utils package (like imageFile) and have the loadCSV method in Model simply use the csvFile class.
