Unix I-Ching Generator 0.8.1

Unix I-Ching Generator project is an I Ching generator for the Unix command line.
It accepts questions and generates responses that can be looked up in the I Ching (a Chinese divination book).
It is designed around "spiritual algorithms", that is, algorithms that make some sort of sense spiritually, not just programatically.
This is software that automates the casting of I-Ching hexagrams. It does not provide the interpretations or readings of those hexagrams.
It merely outputs a mandella of two hexagrams and then informs you of the numerical identity of each hexagram.
Enhancements:
- Moved global options to header file. (ARJ)
- Changed unigram::cast() so that it relied on globals. (ARJ)
- Fixed spelling errors. (ARJ)
