The current version provides implementations of smart pointers, directed 
graphs, sets, maps, B-trees, stacks, tables, string editing, unbounded 
arrays, expression analyzers, lock-free data structures, synchronization 
primitives (events, race condition free pulse events, arrays of events, 
reentrant mutexes, deadlock-free arrays of mutexes), arbitrary precision 
arithmetic, pseudo-random non-repeating numbers, symmetric encoding and 
decoding, IEEE 754 representations support, streams, persistent storage, 
multiple connections server/client designing tools and protocols 
implementations.

The focus of this release is an implementation of arbitrary precision 
rational numbers. The difference to standard library 
Ada.Numerics.Big_Numbers.Big_Reals:

- No limits, except for the pool size;
- String edit packages representing a number in a usual form (with the 
specified accuracy) rather than as a numerator/denominator ratio;
- An equivalent of Ada.Numerics.Elementary_Functions with rational 
approximations;
- Simple continued fractions support.

Changes to the previous version:

- The package Unbounded_Rationals provides an implementation of 
arbitrary precision rational numbers arithmetic;
- The child package Unbounded_Rationals.Elementary_Functions provides 
approximations in rational numbers of some elementary, trigonometric and 
hyperbolic functions;
- The package Strings_Edit.Unbounded_Rational_Edit provides string 
editing for arbitrary precision rational numbers;
- The package Strings_Edit.Unbounded_Unsigned_Edit was optimized for 
better performance;
- Mixed Unsigned_Integer to Integer operations were added to the package 
Unsigned_Integers;
- The package Unbounded_Rationals.Continued_Fractions provides an 
implementation of simple continued fractions;
- The package Strings_Edit.Continued_Fraction_Edit provides string 
editing for simple continued fractions;
- Bug fixes in List_SetItem Python bindings;
- Check_Error message in Python binding was improved, trace back output 
added;
- Added higher level operations to create Python modules after 
initialization of the Python interpreter;
- Added higher level operations to create Python classes AKA heap types 
after initialization;
- An example of higher level module creation was provided;
- An example of higher level class creation was provided;
- IsInitialized function was added to Python bindings;
- OSX project settings fixed.
