/**
* Takes a spec object and a test object; returns true if the test satisfies
* the spec. Each of the spec's own properties must be a predicate function.
* Each predicate is applied to the value of the corresponding property of the
* test object. `where` returns true if all the predicates return true, false
* otherwise.
*
* `where` is well suited to declaratively expressing constraints for other
* functions such as [`filter`](#filter) and [`find`](#find).
*
* @func
* @memberOf R
* @since v0.1.1
* @category Object
* @sig {String: (* -> Boolean)} -> {String: *} -> Boolean
* @param {Object} spec
* @param {Object} testObj
* @return {Boolean}
* @see R.propSatisfies, R.whereEq
* @example
*
* // pred :: Object -> Boolean
* const pred = R.where({
* a: R.equals('foo'),
* b: R.complement(R.equals('bar')),
* x: R.gt(R.__, 10),
* y: R.lt(R.__, 20)
* });
*
* pred({a: 'foo', b: 'xxx', x: 11, y: 19}); //=> true
* pred({a: 'xxx', b: 'xxx', x: 11, y: 19}); //=> false
* pred({a: 'foo', b: 'bar', x: 11, y: 19}); //=> false
* pred({a: 'foo', b: 'xxx', x: 10, y: 19}); //=> false
* pred({a: 'foo', b: 'xxx', x: 11, y: 20}); //=> false
