This commit adds `prelude::*` all doc examples and widget::* to those
that need it. This is done to highlight the use of the prelude and
simplify the examples.
- Examples in Type and module level comments show all imports and use
`prelude::*` and `widget::*` where possible.
- Function level comments hide imports unless there are imports other
than `prelude::*` and `widget::*`.
Reorder the derive fields to be more consistent:
Debug, Default, Clone, Copy, Eq, PartialEq, Ord, PartialOrd, Hash
Hash trait won't be impl in this PR due to rust std design.
If we need hash trait for f64 related structs in the future,
we should consider wrap f64 into a new type.

Implement `Debug & Default` common traits for most structs in src.
