In order to use segtree class defined above, you will need to create a datatype(a struct most likely), which will implement the function merge(). It can also additionally implement split, if you need to define the split operation.
A sample is shown as "struct segtree_node" in the code above.
The segtree has to be instantiated with this defined data type. For example,as
segtree<segtree_node> s;
You have to first call the init function of the class, which will take

node[] = your inital array,
identity = an element such that merge(y,identity) = merge(identity,y) = y for all y's.
