This commit introduces the `Strata.Excel.Core` project, a .NET library built on ClosedXML for robust Excel document generation and data import. Key features include: - **Export:** Flexible data export to Excel, supporting custom formatting, titles, subtitles, humanized headings, and batched processing for large datasets. Includes `ExcelContentResult` and `ZipFileContentResult` for ASP.NET Core integration. - **Import:** Utilities to easily import data from Excel worksheets into C# objects. - **Test Utilities:** Comprehensive helpers for comparing Excel workbooks in tests, handling resource extraction, and performing load tests. - **Build Infrastructure:** Sets up a Dockerfile for building the library, including SonarQube and Dependency-Check scanning. - **Project Structure:** Establishes `.gitignore`, `.dockerignore`, `nuget.config`, and a `README.md` with usage instructions and versioning guidelines. This foundational commit provides a reusable and well-tested framework for Excel operations within Strata applications.
