"""Make sure that the snippets array has a Snippet entry for every week.
The db may have holes in it -- weeks where the user didn't write a
snippet. Augment the given snippets array so that it has no holes,
by adding in default snippet entries if necessary. Note it does
not add these entries to the db, it just adds them to the array.
Arguments:
existing_snippets: a list of Snippet objects for a given user.
The first snippet in the list is assumed to be the oldest
snippet from that user (at least, it's where we start filling
from).
user: a User object for the person writing this snippet.
user_email: the email of the person whose snippets it is.
today: a datetime.datetime object representing the current day.
We fill up to then. If today is wed or before, then we
fill up to the previous week. If it's thurs or after, we
fill up to the current week.
Returns:
A new list of Snippet objects, without any holes.
