tree.hh

Tree.hh is a versatile, templated tree class that operates with C++ and is compatible with the STL algorithms. It is based on the STL's generic programming principles and it can be used for various purposes.

The code below shows a simple example of how to use Tree.hh. The program creates a tree of std::string nodes and then populates the nodes with content. Finally, the program applies the find algorithm to retrieve the node that contains the string "two" and prints out the content of all its children.

```cpp
#include
#include
#include
#include "tree.hh"

using namespace std;

int main(int, char **) {
tree< string > tr;
tree< string >::iterator top, one, two, loc, banana;

top=tr.begin();
one=tr.insert(top, "one");
two=tr.append_child(one, "two");
tr.append_child(two, "apple");
banana=tr.append_child(two, "banana");
tr.append_child(banana,"cherry");
tr.append_child(two, "peach");
tr.append_child(one,"three");

loc=find(tr.begin(), tr.end(), "two");

if(loc!=tr.end()) {
tree< string >::sibling_iterator sib=tr.begin(loc);
while(sib!=tr.end(loc)) {
cout << *sib << endl;
++sib;
}
}
return 0;
}
```

The above code is available as a downloadable source "tree_example.cc" file. Tree.hh provides an easy way to create, populate, and organize a tree of nodes. It is especially convenient for managing complex data structures such as hierarchical data. The library is well-documented and comes with detailed examples to guide users on how to use it effectively.
