Contributions summary:Martin's contributions focused on implementing new assertion methods within the Fluent Assertions library, primarily for string-related assertions. These included implementing `NotStartWith`, `NotEndWith`, `NotStartWithEquivalentOf`, and `NotEndWithEquivalentOf` functionality, alongside other string assertions. The user also made related changes to support assertions on method and property information, with the added implementation of `BeApproximately()` for decimal values. These changes expanded the capabilities of the library, allowing for more thorough testing.
