Recommend items from the reading list

[The4thLaw]

Description

Once Demyo records when the reader marks an item as read, it could start recommending something to read next. It could recommend one of each of the following :

• Something in the same series as a recent read (< 3 months), if there is anything (see Store the albums read by the readers. #49)
• Something in a favourite series
• Something at random

In general, always factor the series with the least pending albums. The date of acquisition should also play a role.

Obviously, if multiple albums from a Series match, only the first one should be recommended.

Albums would only be taken from the reading list.
