User adds a task

The sequence of events in order to add a task is as follows:

The tasks controller loads (by default) the index() function. The index() function checks whether the form validation is false:
```
if ($this->form_validation->run() == FALSE) {
...
```
As this is the first load and the form has not been submitted, it will equal false. The index() function then defines the settings for the task_desc text field, calls the get_tasks() function of Tasks_model (which returns all tasks from the database), and then loads the view files, passing the database object to the views/tasks/view.php file.
The user enters the Chase meeting room booking string, selects a date three days into the future, and clicks on Add to submit the form.
The form is submitted and index() validates the task_desc form elements and the three date dropdowns...
