Negmas

--------------

- Adding new callbacks to simplify factory manager development in the SCM world: on_contract_executed,
on_contract_breached, on_inventory_change, on_production_success, on_cash_transfer
- Supporting callbacks including onUfunChanged on jnegmas for SAONegotiator
- Installing jenegmas 0.2.6 by default in negmas jengmas-setup command

--------------

- updating run scml tutorial
- tox setting update to avoid a break in latest pip (19.1.0)
- handling an edge case with both partners committing breaches at the same
time.
- testing reduced max-insurance setting
- resolving a bug in contract resolution when the same agent commits
multiple money breaches on multiple contracts simultaneously.
- better assertion of correct contract execution
- resolving a bug in production that caused double counting of some
production outputs when multiple lines are executed generating the
same product type at the same step.
- ensuring that the storage reported through awi.state or
simulator.storage_* are correct for the current step. That involves
a slight change in an undocumented feature of production. In the past
produced products were moved to the factory storage BEFORE the
beginning of production on the next step. Now it is moved AFTER the
END of production of the current step (the step production was
completed). This ensures that when the factory manager reads its
storage it reflects what it actually have at all times.
- improving printing of RunningCommandInfo and ProductionReport
- regenerating setup.py
- revealing jobs in FactoryState
- handling a bug that caused factories to have a single line sometimes.
- revealing the dict jobs in FactoryState which gives the scheduled jobs
for each time/line
- adding always_concede option to NaiveTitForTatNegotiator
- updating insurance premium percents.
- adding more tests of NaiveTitForTatNegotiator
- removing relative_premium/premium confusion. Now evaluate_premium will
always return a premium as a fraction of the contract total cost not
as the full price of the insurance policy. For a contract of value 30,
a premium of 0.1 means 3 money units not 0.1 money units.
- adding --config option to tournament and scml commands of negmas CLI
to allow users to set default parameters in a file or using
environment variables
- unifying the meaning of negative numbers for max_insurance_premium to
mean never buying insuance in the scheduler, manager, and app. Now you
have to set max_insurance_premium to inf to make the system
- enforcing argument types in negmas CLI
- Adding DEFAULT_NEGOTIATOR constant to apps.scml.common to control the
default negotiator type used by built-agents
- making utility_function a property instead of a data member of
negotiator
- adding on_ufun_changed() callback to Negotiator instead of relying on
on_nofitication() [relying on on_notification still works].
- deprecating passing dynamic_ufun to constructors of all negotiators
- removing special treatment of AspirationNegotiator in miners
- modifications to the implementation of TitForTatNegotiator to make it
more sane.
- deprecating changing the utility function directly (using
negotiator.ufun = x) AFTER the negotiation starts. It is
still possible to change it up to the call to join()
- adding negmas.apps.scml.DEFAULT_NEGOTIATOR to control the default negotiator used
- improved parameter settings (for internal parameters not published in the SCML document)
- speeding up ufun dumping
- formatting update
- adding ufun logging as follows:

* World and SCMLWorld has now log_ufuns_file which if not None gives a file to log the funs into.
* negmas tournament and scml commands receive a --log-ufuns or --no-log-ufuns to control whether
or not to log the ufuns into the tournament/world stats directory under the name ufuns.csv

- adding a helper add_records to add records into existing csv files.

--------------
- minor bug fix

--------------

- adding more control to negmas tournaments:

1. adding --factories argument to control how many factories (at least) should exist on each production
level
2. adding --agents argument to control how many agents per competitor to instantiate. For the anac2019std
ttype, this will be forced to 1

- adding sabotage track and anac2019_sabotage to run it
- updating test assertions for negotiators.
- tutorial update
- completed NaiveTitForTatNegotiator implementation

-------------

- resolving a bug in AspirationNegotiator that caused an exception for ufuns with assume_normalized
- resolving a bug in ASOMechanism that caused agreements only on boundary offers.
- using jnegmas-0.2.4 instead of jnegmas-0.2.3 in negmas jnegmas-setup command

-------------

- adding commands to FactoryState.
- Allowing JNegMAS to use GreedyFactoryManager. To do that, the Java factory manager must inherit from
GreedyFactoryManager and its class name must end with either GreedyFactoryManager or GFM
