Logger-enabled algorithms should use the exclamation mark in their name

[saxarona]

Take for example the oneplusone signature:

oneplusone(logger::Logbook, f, ind, k_max, M)

Since logger is being modified by the compute! function inside, then oneplusone should have an exclamation mark in the name as well.

This would make the difference between oneplusone and oneplusone! easier to notice, as well.

• oneplusone!
• GA!
• PSO!
