v1.2.0

Fixed

• issue with various filter tyes and random drop filters
• a few minor issues with C api (helicsFederateSetMaxIterations)
• potential threading issues when updating the logger on an executing federate
• federates will now propagate errors properly for duplicate publications and endpoints
• federates will now error on missing required publications

Changed

• implement use of fmt library instead of boost::format
• improved python installation scripts
• general threading and refactoring of the core
• automatic name generation no longer uses random uuid's, but a shorter 20 character random string

Added

• queryCoreExecute, queryBrokerExecute to the C api to allow queries to be executed directly on brokers and cores
• C++ API changes to Brokers and Core's to allow queries directly
• new queries (federate_map, and dependency_graph(partial))
• additional filter tests and query tests
• realtime mode for HELICS specified by activating the realtime flag, and specifying rt_lag and rt_lead the federate will then delay grant or force_grant based on computer clock to match wall time.
