Change the print method to return a value instead of directly calling console.log.Unify the logic of all keyValueOrEntryOrRawElementToNode methods in BinaryTree.
Use a generic isComparable method to determine if a value is comparable in size when using the isKey method in the BinaryTree. Fix the boundary value bug in the getNodes method of BinaryTree. Support callback functions in getLeftMost and getRightMost to support returning results with different properties. If a comparator is specified for BST, the isKey method will force the object type to be comparable. The isComparable method has been implemented based on JavaScript's comparison principles.
