Splits values into two groups.

@param {Collection} collection - input collection
@param {Options} [options] - function options
@param {string} [options.returns="values"] - if `values`, values are returned; if `indices`, indices are returned; if `*`, both indices and values are returned
@param {Collection} filter - collection indicating which group an element in the input collection belongs to
@throws {TypeError} first argument must be a collection
@throws {TypeError} options argument must be an object
@throws {TypeError} must provide valid options
@throws {TypeError} last argument must be a collection
@throws {RangeError} first and last arguments must be the same length
@returns {(Array|ArrayArray)} results

@example
var arr = [ 'beep', 'boop', 'foo', 'bar' ];
var filter = [ true, true, false, true ];

var out = bifurcate( arr, filter );
// returns [ [ 'beep', 'boop', 'bar' ], [ 'foo' ] ]

@example
var arr = [ 'beep', 'boop', 'foo', 'bar' ];
var filter = [ true, true, false, true ];

var opts = {
    'returns': 'indices'
};

var out = bifurcate( arr, opts, filter );
// returns [ [ 0, 1, 3 ], [ 2 ] ]

@example
var arr = [ 'beep', 'boop', 'foo', 'bar' ];
var filter = [ true, true, false, true ];

var opts = {
    'returns': '*'
};

var out = bifurcate( arr, opts, filter );
// returns [ [ [ 0, 'beep' ], [ 1, 'boop' ], [ 3, 'bar' ] ], [ [ 2, 'foo' ] ] ]
