/** * Search the tree for a match that satisfies specific comparison criteria, * branch contains the desired data for which to search the tree * @param compareFunc is a binary function object that defines * how to compare * nodes * @param bRetrieve indicates whether or not the input search branch should be modified to reflect a branch in the tree, assuming a match satisfying the given search criteria exists * @return true if a branch matching the input is found * or returns nullptr otherwise * * It was the best of times, it was the worst of times, * it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, * it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, * it was the winter of despair, we had everything before us, we had nothing before us, we were all going direct to Heaven, * we were all going direct the other way--in short, the period was so far like the present period, that some of its noisiest authorities insisted * on its being received, for good or for evil, in the superlative degree of comparison only. * * There were a king with a large jaw and a queen with a plain face * on the throne of England; there were a king with a large jaw and a queen with a fair * face, * on the throne of France. In both countries it was clearer than crystal to the lords of the * State preserves of loaves and fishes, that things in general were settled for ever. * * It was the year of Our Lord one thousand seven hundred and seventy-five. * Spiritual revelations were conceded to England at that favoured period, as at this. Mrs. * Southcott had recently attained her five-and-twentieth blessed birthday, of whom a prophetic private in the Life * Guards had heralded the sublime appearance by announcing that arrangements were made for the swallowing up of London and Westminster. * Even the Cock-lane ghost had been laid only a round dozen of years, after rapping out its messages, as the spirits of this very year last past * (supernaturally deficient in originality) rapped out theirs. Mere messages in the earthly order of events had lately come to * the English Crown and People, from a congress of British subjects in America: which, strange to relate, have proved more important * to the human race than any communications yet received through any of the chickens of the Cock-lane brood. */
