Release 0.10.0: new internal representation with full cQASM 1.2 control-flow support

Added

• scalability options for coping with large multi-core systems, including a progress bar for the mapping process
• initial implementation of the Diamond architecture developed for Fujitsu (lead by Stephan Wong)
• full cQASM 1.2 read and write support, with options for different version levels and various language quirks
• new internal representation that encompasses the entire cQASM 1.2 language, and has many new generalized platform features
• lossless conversion functions between the two IR representations until all passes have been converted to the new representation
• new pass-based decomposition logic that supports arbitrary cQASM 1.2 code for the expansion and doesn't clobber scheduling information
• new pass for converting structured cQASM 1.2 control flow to basic block form
• new list scheduler based on the new IR

Changed

• all written cQASM files are now in 1.2 format by default
• the cQASM reader no longer has a JSON configuration file for mapping cQASM gates to OpenQL gates; this translation is now part of OpenQL's platform data
• the old scheduler is replaced with a new implementation for most option variations, that outputs slightly different schedules
• statistics report output is also formatted slightly different, though information content is the same
• CC backend:
  • scheduling is now done using resource constraints by default

Fixed

• excessive memory usage and slow platform construction for large multi-core systems
