2a222adb7e Represent character sets with unsigned chars 
This is better for comparing character ranges, since

were given, for resolving reduce/reduce conflicts.

5ed5ae7514 In LR(1) items, only store consumed symbols as booleans 
the booleans represent the symbols point to auxiliary tokens

parse tables. Any other information just leads to redundant
parse states.
