A bit more finished

... the book, that is.

I'm updating it since grammar is now finished, and all the polish it needs shouldn't mess with designs, rules, pieces. I say shouldn't, because I bit my tongue so many times already.

Updates include mostly grammar, and some side clarifications, like how to combine multiple side-effects, added some examples on how to diverge,  material pieces are now gaining 1 momentum when diverging from Starchild, all small stuff.

One thing that still bothers me, although much less so then before is that grammar alone (that is, without context) is not be-all-end-all reference. I have wrote it in the book, but it's worth repeating: entity (values) which are present only sometimes are not the same as optional entity (values). 

For instance, move status most of the time is not present, i.e. it's empty value. Except for checks, all other move statuses are mandatory to write. To sort-of convey that mandatory-ness to reader, I defined move status with an empty value, so that status after a move is mandatory not just in notation, but in grammar as well.

Similarly, Shaman stepping is not defined entirely correctly; issue is that Shaman has ordinary steps separated from capture-steps, and can switch between the two after diverging. Wave can be ignored only while making ordinary steps, but not capture-steps. However, both transparency and  capturing side-effects are optional to write, and so both steps could look the same. So, to keep things simple, I lumped all side-effects together, even though they are separated.

Lack of meaning isn't something that can be solved in grammar, and the book can only deliver so much, or so little. In the end, it's up to reader to build his/her own understanding. 

Anyways, back to the drawing coding board.
