`dictionary` is a dict containing two types of entries:
- for normal text pages, id: (title, text).
`text` may contain interpolation fields, such as {code}.
When that's the case, there must be an 2nd-type entry for "code" in this dict.
`title` may be None.
- for interpolation codes, code: text.
`text` is the text to be used for the interpolation.
`dictionary` is a dict containing two kinds of entries:
- the first kind is to store the possible pages which can be added to the dict.
These entries are the form {str page_id : (str|None page_title, str page_text)}.
`page_text` may contain interpolation fields, such as {code}.
- the second kind is to store the for interpolation codes to fill in those blanks.
These entries are of the form {str interpo_id : str interpo_text}.
`interpo_text` is the text to be used for the interpolation.
See the diary_append method to match interpolation fields with interpolation ids when adding the pages.
Alternatively, `dictionary` may be the name of a store variable containing the actual dictionary
(that's better when not in a testing phase, for pickling/saving/updating reasons)

Adds a page to the diary.
`id` is the key of the event that just happened, in the dictionary.
`id` is the key of the event that just happened, in the dictionary - a first-kind key.
`day` sets the day number for the entry, defaulting to the current day.
`branches` is a dict of {sub-event id : code} for every happened sub-event specializing event `id`.
the specified codes will be looked for in the dictionary, and the original entry of id `id`
will be formatted by associating {sub-event id} with dictionary[code].
If `code` is not a valid entry in the dict, the `code` value itself will be interpolated instead,
or nothing if v is a false value (like None).
`branches` is a dict of {code : interpo_id} for every happened sub-event specializing the `id` event.
The specified interpolation ids will be looked for in the dictionary, and the original entry of id `id`
will be formatted by replacing {code} with the text found in dictionary[interpo_id].
If `interpo_id` is not a valid entry in the dict, the passed value itself will be interpolated instead,
or nothing if it is a false value (like None).
If the page for the key `id` contains interpolation fields,
it is a mistake to not specify all interpolation fields in `branches`.
It is benign to specify keys which are not interpolation fields.
For example, if the entry associated with "id1549" is ("Tittle", "Today I met {a} and did {b}. I liked it{c}.").
Calling `diary_append("id1549", a="Alice", b="nothing", c=" a lot")` will add the page
"Today I met Alice and did nothing. I liked it a lot." to the diary, with the title "Tittle".
Passing c="" or c=None or c=False will all result in "Today I met Alice and did nothing. I liked it.".
If the page for the key `id` contains interpolation fields, it is a mistake
not to pass all interpolation fields.
It is benign to specify keys which are not interpolation fields in the entry : in the previous example,
passing d=whatever will not change anything to the result.
Passing the same page `id` several times will only work the first time, subsequent tries will be ignored.
The entry_id attribute (a set) can be accessed, read only, to check if an entry has already been added.
