Translate the code from C# to C++

[konard]

🚀 Complete C# to C++ Translation

This pull request successfully translates the Platform.Incrementers library from C# to C++.

📋 Issue Reference

Fixes #15

✅ Implementation Details

Translated Files:

• IIncrementer.h - Base incrementer interface
• IIncrementer[TNumber].h - Generic number incrementer interface
• Incrementer.h - Base incrementer implementation with template specialization
• Incrementer[TValue, TDecision].h - Template incrementer with custom decision type
• Incrementer[TValue].h - Template incrementer with boolean decision type
• IncrementerTests.cpp - Complete unit tests

Key Features:

• ✅ Proper C++ template specializations and inheritance hierarchy
• ✅ Correct constructor initialization syntax
• ✅ Modern C++ features (explicit constructors, default constructors, const methods)
• ✅ Virtual destructor for proper inheritance
• ✅ Proper header guards and includes
• ✅ Comprehensive test coverage matching C# functionality
• ✅ Compilation verified with g++ (C++17 standard)

Template Structure:

Incrementer<>                          // Base specialization
├── Incrementer<TValue, TDecision>     // Two-parameter template  
    └── Incrementer<TValue>           // Single-parameter (inherits with bool)

🧪 Testing

• All template specializations compile successfully
• Functional tests verify correct behavior:
  • Basic increment operations
  • Template parameter handling
  • Custom return type functionality
  • Constructor variations

📝 Translation Notes

The C++ version maintains full compatibility with the C# API while using idiomatic C++ patterns:

• Properties become const member functions
• Template specializations handle generic types
• RAII principles for resource management
• Modern C++ constructor delegation
