Detailed Description

template<typename T>
class chomp::homology::auto_array< T >

An auto_array template that mimics selected behaviors of the std::auto_ptr template, but releases the memory with delete[], and thus should be applied to arrays.

This template is based on what I found in the g++ header file "memory".
