Fixes #11. Presets are groups of settings and values applied at once. This is used as a shorthand in test files, so for example "isa intel nehalem" enables all of the CPUID bits that the Nehalem micro-architecture provides.
Wherein we learned that only BoolSettings can be used as predicates.
- cdsl.predicates defines classes for describing predicates. - cdsl.settings defines classes for describing settings. - base.settings defines shared settings.
