// RAVEN STANDARD TEMPLATE LIBRARY
//  (c) 2002 Activision
//
//
// Common
// ------
// The raven libraries contain a number of common defines, enums, and typedefs which
// need to be accessed by all templates.  Each of these is included here.
//
// Also included is a safeguarded assert file for all the asserts in RTL.
//
// This file is included in EVERY TEMPLATE, so it should be very light in order to 
// reduce compile times.
//
//
// Format
// ------
// In order to simplify code and provide readability, the template library has some
// standard formats.  Any new templates or functions should adhere to these formats:
//
// - All memory is statically allocated, usually by parameter SIZE
// - All classes provide an enum which defines constant variables, including CAPACITY
// - All classes which moniter the number of items allocated provide the following functions:
//     size()   - the number of objects
//     empty()  - does the container have zero objects
//     full()   - does the container have any room left for more objects
//     clear()  - remove all objects
//
//
// - Functions are defined in the following order:
//     Capacity
//     Constructors  (copy, from string, etc...)
//     Range		 (size(), empty(), full(), clear(), etc...)
//     Access        (operator[], front(), back(), etc...)
//     Modification  (add(), remove(), push(), pop(), etc...)
//     Iteration     (begin(), end(), insert(), erase(), find(), etc...)
//
//
// NOTES:
//
