Max different buildings per day (#58)

For each class, teacher or subject you can specify a maximum number of buildings per day with an advanced card relationship nb 58.

Note:
Keep in mind, that similar constraints about transits between buildings were already added with the buildings creation.
Please, see this: Transfers between buildings

Here are some examples for using this relation:

1. Class 5.A can be in no more than 2 different buildings in a day for every subject:
This mean, that if you have more school's building, program can choose the classrooms for lessons only from two buildings.
However, please keep in mind that this doesn't specify the number of transits the students can have during a day. They can have 2 buildings, but 4 transits per day.

2. For more precise specification of transits between buildings for classes, you can use a time map for this card relationships.
In following card relationship is specified that students must be in one building only on periods 3,4,5. It means, that they cannot transit between 3/4 and 4/5. By using more similar relations (for different parts of a day) you can limit transits for classes a you need.

3. In case that students can transfer only for specified subject (e.g. Physical education) and no transfer for other lessons, you can simply set max buildings to no more than 1 AND exclude required subject from the list.in the filter field
This is useful, if you have e.g. only one sport complex where students must transfer to, but otherwise you wish to keep all their lessons in one building only.
