Remove and complete function

Now that the adding function is completed the complete and remove function has been implemented. These are vital components of any ToDo List. Below is a screenshot of the buttons which the user can control:

The remove button will remove a ToDo List entry and the complete button will put a strike through the ToDo List entry to symbolise that it is complete. The toggle all checkbox selects all the entries to save the user time selecting all the entries by hand. The advanced feature removes all visibility of the category and date information. This saves the user from entering in a date and category for fast input. This would be useful with an ongoing reminder such as buying milk.
