RISC-V supported (Thanks to Lucas Elvira Martín @luck5941)
CREATOR accessibility improved up to WCAG 2.0 (Level AAA)
Command line version of CREATOR:
- Help:
  - ./creator.sh -h
- Example: creator compiles and executes the example2.txt, showing the final state:
  - ./creator.sh -a architecture/MIPS-32.json -s examples/MIPS/example2.txt
- Example: save final state into 'output.txt' file:
  - ./creator.sh -a ./architecture/MIPS-32.json -s ./examples/MIPS/example2.txt -o min > output.txt
- Example: compare the final state and the state saved on 'output.txt' file:
  - ./creator.sh -a ./architecture/MIPS-32.json -s ./examples/MIPS/example2.txt -o min -r output.txt
Creator now accepts three GET values:
- Preload the MIPS architecture:
  - https://creatorsim.github.io/creator/?architecture=MIPS-32
- Preload example 'e3' from example set 'uc3m-ec':
  - https://creatorsim.github.io/creator/?example_set=uc3m-ec&example=e3
