Pluralize.NET.Core

This is a C# port of Blake Embrey's pluralize library which helps in pluralizing or singularizing any English word. Originally from Sarath Kumar CM: "I could not find a good C# alternative for converting words from singular to plural and vice versa. System.Data.Entity.Design.PluralizationServices.PluralizationService and Humanizer library did not meet the expectations (try 'shoes' or 'toes'). However this small but awesome Javascript libray pluralize worked very well for me and I decided to convert the code to C# and use it. I forked, migrated and compiled this into .NET Standard 2.0. This code does exactly what I need without the bulk. Much respect to Mr Embrey (the original code) and Mr Kumar (for the original port).
