Force fields

Update the internal data structures of the force field when the system changes (e.g., through coordinate updates)

Please note that changes to the options or the topology require a call to setup!prior to the call to$update!$``.

read_ball_ini_file(path::String; ...) -> BALLIniFile
read_ball_ini_file(
    path::String,
    T;
    cleanup_keys
) -> BALLIniFile

Read a file in BALL's old Ini file format and return it as a BALLIniFile.

If cleanup_keys is set to true (the default), keys into the Ini sections are simplified (e.g., ver:version becomes version, key:I becomes I, ...).
