- Compiler changes to gcc 4.8.2
- Wrong handling of defining functions in SeqDef corrected.
- Storing callables as std::function in mapping sequences and
  generating sequences to avoid crash (temporary solution).
- Store typed callables instead of std::function in mapped sequences
- Storing typed callables instead of std::function in generating
  sequences.
- Utility for determining type for storing callables created.
- Skeleton for parallel sequences created
- Live time issue for inner sequences fixed (always copy inner
  sequences)
