* ## Notes
*
* -   The predicate function is provided three arguments:
*
*     -   `value`: object value
*     -   `key`: object key
*     -   `obj`: the input object
*
* -   The function immediately returns upon finding `n` successful properties.
*
* -   If provided an empty object, the function returns `false`.
*
* @param obj - input object
* @param n - number of properties
* @param predicate - test function
* @returns boolean indicating whether an object contains at least `n` own properties which pass a test
*
* @example
* function isNegative( v ) {
*     return ( v < 0 );
* }
*
* var obj = { a: 1, b: 2, c: -3, d: 4, e: -1 };
*
* var bool = someOwnBy( obj, 2, isNegative );
* // returns true
