// COMMENTED OUT CODE DISCLAIMER
// To ensure compilation for the other files with the BigInt.hpp or any other external header files, this entire file is commented out. 
// In the current structure that only uses one file at a time, header files are not perfectly organised.
// Having many files in a project you have no intention of using is not a normal use case, therefore organising this perfectly is not a priority.
// To test this file, get the BigInt hpp file from github and add it to the Header Files, in my case in a "libs" filter. 
// Comment out any other cpp files using it. Only the .cpp files should need to be edited.

//* Several methods used in this project would be a good fit for extension methods.
//* Given the structure of the project this could lead do dependency issues.
//* The scope for every file is also small enough to not need it.
