Decent Exposure

Replaces verbose finder and builder patterns with a simple `expose` macro, as shown in the example controller, drastically cutting down on repetitive boilerplate code.

Offers extensive options like `find_by` for slug-based lookups and `scope` for custom queries, allowing adaptation to various use cases beyond standard Rails conventions.

Supports lazy evaluation with `expose` to avoid unnecessary database queries, and eager loading with `expose!` via a before filter, enabling performance tuning based on action needs.

The `exposure_config` method allows saving and reusing exposure settings across multiple controllers or mailers, promoting DRY code and consistency in larger projects.

Extends the same DSL to Rails mailers, as demonstrated in the example mailer, simplifying object exposure in email templates without requiring separate setup or patterns.
