Add courses component

[paulbert]

The courses component will need to be implemented in a few steps. Let's start with the form so we can populate a courses database. It should:

• Add a document to the database with the form fields found in the current BeLL-Apps on a form submit click with the exception of the attachment
• Not add a document if a resource with the same title currently exists
• Be linked to from the COURSES nav link

Notes:

• No need to bother with the real text editor, you can just use a plain textbox description for now.

For reference, here's the current add courses form:

courses.component.ts

• I'd put the form options on lines 26-53 into a separate file at this point. This file is a little large, and I don't think those defaults will change as much as the form methods.
• I'd rather we didn't add then delete a resource if the title is a duplicate. I like the use of CouchDB design docs, and I imagine there's a solution there which would solve this. Alternatively, you can query the database with /_find and don't add the document if there is a result. Either way, we wouldn't need to use the courses-checker.json as well.
• You don't need an ngOnInit to initialize the form values. You can just do that in createForm.
• For the toggleWeekly() method I think it would be simpler to loop once through the day formArray and remove each value that had been pushed.

courses.component.html

• The cancel button should be of type="button" rather than type="submit" so it does not run the onSubmit code when clicked.

custom-validators.ts

• First, I don't think is needed since the input type="number" limits it to a number and we can use the built in min validator (see here) to make sure it is a positive number.
• This also throws an error since the value is actually stored as a number and the .match method is only a method of strings. This error seems to be breaking the cancel() method.

CouchDB design docs

• I think these should go into a different folder, maybe called design

I have fixed most of the issues you talked about. Now, I need to work on validators.
