change wording: replace abm migration by mobility and epi by mio

[xsaschako]

Provide a description of requested documentation changes.

Change all occurrences from migration to movement.

[xsaschako]

I'll probably also rename epi to mio while i'm at it

[xsaschako]

There are several phrases to change and we need to decide if we want to rename it into mobility or movement, e.g.:

• Person::migrate_to
• migration
• MigrationEdge
• make_migration_sim
• time step of migration, daily migration every second step
• migration data
• migration_destination
• use_migration_rules
• apply_migration
• forward migration

[xsaschako]

We decided on:

• mobility if not a verb
• go (to) as a verb (comment functions with “mobility” keyword)

We decided on:

• mobility if not a verb
• go (to) as a verb (comment functions with “mobility” keyword)

For now, I renamed everything to "movement" or "move_to". Didn't read this comment before doing so. I can redo it and call it mobility. Perhaps we decide on this quickly.

[DavidKerkmann]

Since there were still some unclear points and no perfect naming, we discussed in a group an propose:

• "mobility" if not a verb
• "commuted" for the "migrated" vector in the graph-ode parts (MobilityEdge)
• "change_location" for the ABM function to change a single persons location
• "perform_mobility" for the large ABM function that handles all the mobility

@mknaranja Do you agree with this?

[DavidKerkmann]

Instead of "commuted", we use "mobile_population".

[DavidKerkmann]

There are many appearances of "moved" or "move" that were previously "migrated" or "migrate" which relate to a verb, in particular in memilio/cpp/memilio/mobility/metapopulation_mobility_instant.h. We need to have a verb for these, if we use "mobile_population" as a noun.

[jubicker]

We only need verbs for the documentation right? Because the parameters "migrated", "return_migrated" etc. will be renamed to "mobile_population", "return_mobile_population". For the documentation verbs could be "change location" in the ABM and "change node" in the Graph model.
