Simple components for Ada4.57

This library provides implementations of smart pointers for automatically collected objects (using reference counting); database-indpendent object persistence through ODBC or SQLite with persistent objects that may depend on other objects; various containers including doubly-linked webs and lists, directed graphs, directed weighted, maps, stacks, sets, bounded and unbounded arrays; containers of handles to objects; table management with parsing support; text editing tools for string formatting of integer and floating-point numbers in any base; OO parsers for infix expressions with varios examples from a simple console calculator to full Ada 95 expressions parser; storage pools; IEEE 754 numbers; lock-free shared structures including FIFO and blackboard. Synchronization primitives include events, pulse events, pulse events distributing values, arrays of events which can be signaled, reset and awaited for an arbitrary combination of, race condition free. It also includes reentrant mutexes and arrays of mutexes with an enforced locking policy, race condition free, SQLite bindings, block and memory resident streams.
