- Switched most symbolic signed constants to unsigned variants. Redefined EOF in particular to become (size)-1, to avoid having to use signed token type values.
- Introduced INVALID_INDEX for all previous -1 values to indicate e.g. not found indexes etc.
- Added 2 helpers to convert between symbolic and numeric form (mostly for intervals and toString()).
- Removed many no longer needed type casts to size_t.
- Updated templates for these changes.
- Limited runtime tests to C++ tests only, to see how Travis CI copes with that.
In order to lower the overhead when passing around Token instances via smart pointers and because the ownership is clear (token streams own them), these instances can be passed as raw pointers.
