Negmas

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

* [core] making the core SAONegotiator robust to missing ufuns.
* [core] allowing controllers to control the ID of negotiators
* [core] adding methods to find partner IDs and names
* [sao] Adding global_ufun to SAOSyncController
* [core] removing all all_contracts.csv from output keeping only contracts.csv withe full information.
* [core] Added serialization module for serializing objects in human readable format.
* [core] Added id as a parameter to all constructors of NamedObjects
* [core] dividing utilities.py into multiple modules
* This should not affect any external users.
* [core] removing an issue when deepcopying utility fucntions.
* [core] adding inverse_utility support
* [core] adding inverse ufun support
* [cli] removing unnecessry force flag
* [sao] adding allow_offering_just_rejected_offers
* [core] adding max_n_outcomes to Issue.sample
* adding parameters to mechanisms and worlds.
* [genius] improved the information on ANAC competition
* [genius] restructuring the module into a package
* [core] bugfix in LinearUtilityFunciton that calculated the weights
* incorrectly sometimes
* [genius] Adding close_gateway to GeniusBridge to close all connections
* [genius] Adding close_gateway to GeniusBridge to close all connections
* [genius] Added GeniusBridge with methods to control a bridge
* [genius] Now all GeniusNegotiator classes share the same bridge to avoid too much resource allocation but this may not be safe when running tournaments.
* [genius] compatible with bridge version 0.5
* [genius] compatible with bridge v0.3
* [genius] more exhaustive testing and resolving ending issue
* [genius] adding the skeleton to cancel unending agents
* [sao] allowing load_genius_domain to use any kwargs
* [core] adding imap to all mechanisms
* [core] Maps between issue name and index and back
* [core] Speeding issue enumeration
* [core] Enumerating faster for large outcome spaces.
* [core] Adding max_n_outcomes to functions that use outcome enumeration more consistently.
* [core] adding a warning for infinity ufun values
* [inout] bugfix a failure when reading some genius files

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

* [tournaments] Default to faster tournaments
* [testing] Avoid failure on PyQT not installed
* [situated] agreement and contract validation:
Agreement validation (is_valid_agreement) and contract validation
(is_valis_valid_contract) are added to the World class. Using them
a world designer can decide that an agreement (before signing) or
a contract (after signing) is invalid and drop it so it is never
executed. These contracts appear as 'dropped_contracts' in stats.
* [tournaments] Adding max_attempts parameter when running worlds.

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

* [tournaments] Possible exclusion of competitors from dyn. non-comp.
* [tournaments] Adding dynamic non_competitors
* [situated] Allowing more return types from sign_all_contacts
* [tournaments] Avoid different stat lengths
* [situated, tournaments] Early break if time-limit is exceeded.
* [situated, tournaments] Early break if time-limit is exceeded.
* [situated, mechanisms, tournaments] Using perf_counter consistently to measure time.
* [situated,mechanisms] more robust relative time
* [setup] Removing installation of visualizer components in CI
* [tournaments] Avoid failure for empty stat files when combining tournaments
* [helpers] avoid trying to load empty files
* [tournament][bugfix] Error in concatenating multiple exceptions.
* [tournament][bugfix] Serial run was failing
* [situated] Avoiding relative_time > 1
* [mechanisms] Avoiding relative_time > 1
* [tournament] Saving temporary scores in tournaments by default
* [tournaments][bugfix] Tuples were causing exceptions when combining agent exceptions
* [bugfix] correcting NotImplementedError exception
* [situated] Avoid failure when returning non-iterable from sign_all_contracts
* [tournaments] better handling of continuation
* [tournament] Randomizing assigned config runs
* [tournament] adding extra exception and timing information to tournaments
* [docs] Documentation update
* [situated] Keeping details of who committed exceptions.
* [situated] For negotiation exceptions, the exception is registered for the agents
owning all negotiators as it is not possible in World to know the
negotiator from whom the exception originated.

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

* [tournaments] defaulting to no logs or videos in tournaments.
* [base] bugfix: avoid calling parent in passthrough negotiator when it does not exist.
* [base] making PyQT optional

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

* [docs] more tutorials and overview revampment
* [sao] Allowing max_wait to be passed as None defaulting to inf
* [sao] Passing the ufun to the meta-negotiator in SAOMetaNegotiatorController
* [base] unsetting the controller when killing a negotiator
* [base] setting default max_waits to infinity
* [base] defaulting to auto-kill negotiators in all controllers.py
* [base] Adding max_wait to void infinite loops with sync controllers

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

* [base] removing a warning caused by passing dynamic_ufun
* [base] correctly passing ufun to all rational types
* [base] placeholder to support parallel runall in mechanism
* [base] LimitedOutcomesNegotiator does not offer what it will not accept
* [base] Bug fixes in Utilities and LimitedOutcomesNegotiator
* [performance] Caching first offers in SyncController.
* [performance] Reducing memory consumption of AspirationNegotiator
* [performance] Speeding up Mechanism.state
* [performance] Adding eval_all to UtilitityFunction to speedup multiple evaluations
* [docs] Improving the overview part of the documentation
* [docs] Documentation update

* [elicitation] correcting a bug in base elicitor
* [installation] Resolving an issue when blist is not installed
* [installation] Adding gif to requirements
* [installation] warn if gif generation failed
* reformatting and import optimization
* Removing eu from SAONegotiator because we have no opponent_models yet
