Tests if a value is a ragged nested array.

@param {*} value - value to test
@returns {boolean} boolean indicating if a value is a ragged nested array

@example
var bool = isRaggedNestedArray( [ [ 1, 2, 3 ], [ 4, 5 ] ] );
// returns true

@example
var bool = isRaggedNestedArray( [ [ 1, 2, 3 ], [ 4, 5, 6 ] ] );
// returns false

@example
var bool = isRaggedNestedArray( 'beep' );
// returns false
