A router DataSource constructor for falcor that allows you to model all your cloud data sources as a single JSON resource.

module.exports = function catAndSlice(a, b, slice) {
    var next = [], i, j, len;
    for (i = 0, len = a.length; i < len; ++i) {
        next[i] = a[i];
    }

    for (j = slice || 0, len = b.length; j < len; ++j, ++i) {
        next[i] = b[j];
    }

    return next;
};
