This modification impacts all parts of Batsim in which machines were involved.
The protocol has also been updated to allow the scheduler to send machine ranges
in its allocations. The previous syntax is still supported. Now, each comma-separated
value can either be 1 machineID or a range of machineIDs (syntax: machineIDa-machineIDb
to represent the closed interval [machineIDa, machineIDb]).

Please note that Batsim has been only been tested with old schedulers (that do not
support the new protocol syntax).
