Vector implementation in C++ (with iterator)

Raw memory allocation and deallocation, placement new are used for correct operations with complex classes working with memory.

Following methods are implemented:

• size()
• capacity()
• empty()
• reserve()
• at()
• front()
• back()
• data()
• push_back()
• emplace_back()
• clear()
• erase()
• begin()
• end()
• cbegin()
• cend()
• swap()

Iterator realization meets std::random_access_iterator requirements.
Tests are made with CATCH2; buffer.h contains class with memory use (new[], delete[]) for additional tests.
Integration by CmakeLists may require "set_target_properties(vector PROPERTIES LINKER_LANGUAGE CXX)".
