Project 2

- Must run off command line:
  * May specify the input file on the command line.

Use library objects as much as possible
- Grads on 2nd version  minimize library objects

Priority Queue in C++:
template <class T, class Container = vector<T>,
  class Compare = less<typename Container::value_type> > class priority_queue;
  
  - Need only specify the class to fill in for template parameter T.
  - Problem: The default comparator is less<typename Container::value_type>
    * Must specify a different comparator: 
         It's the 3rd argument, so the 2nd argument must also be included

e.g. typedef priority_queue<EdgeObject,vector<EdgeObject>,greater<EdgeObject>()>  EdgeHeap

template <class T, class Container = vector<T>,
  class Compare = less<typename Container::value_type> > class priority_queue;

EdgeObject must be defined for > (greater-than)

- Must justify the sequential container used (vector vs list vs other?)
