[samchon]

Added a new module notations to support naming convention converters.

export namespace notations {
    export function camel<T>(input: T): CamelCase<T>;
    export function assertCamel<T>(input: unknown | T): CamelCase<T>;
    export function isCamel<T>(input: unknown | T): CamelCase<T> | null;
    export function validateCamel<T>(input: unknown | T): IValidation<CamelCase<T>>;

    export function pascal<T>(input: T): PascalCase<T>;
    export function assertPascal<T>(input: unknown | T): PascalCase<T>;
    export function isPascal<T>(input: unknown | T): PascalCase<T> | null;
    export function validatePascal<T>(input: unknown | T): IValidation<PascalCase<T>>;

    export function snake<T>(input: T): SnakeCase<T>;
    export function assertSnake<T>(input: unknown | T): SnakeCase<T>;
    export function isSnake<T>(input: unknown | T): SnakeCase<T> | null;
    export function validateSnake<T>(input: unknown | T): IValidation<SnakeCase<T>>;
}
