Boost Pointer Container Library

# Pointer Container Library

## Usage Guidelines

The recommended usage pattern of the container classes are the same as the for normal standard containers.

`ptr_vector`, `ptr_list` and `ptr_deque` offer the programmer different complexity tradeoffs and should be used accordingly. `ptr_vector` is the type of sequence that should be used by default. `ptr_list` should be used when there are frequent insertions and deletions from the middle of the sequence and if the container is fairly large (eg. more than 100 elements). `ptr_deque` is the data structure of choice when most insertions and deletions take place at the beginning or at the end of the sequence. The special container `ptr_array` may be used when the size of the container is invariant and known at compile time.

An associative container supports unique keys if it may contain at most one element for each key. Otherwise, it supports equivalent keys. `ptr_set` and `ptr_map` support unique keys. `ptr_multiset` and `ptr_multimap` support equivalent keys.
