expect greater equal family of assertions.

* `verify_ge`: verify if actual is greater than or equal to expected and return Result.
* `assert_ge`: exists in rust: https://docs.rs/all_asserts/latest/all_asserts/macro.assert_ge.html
* `expect_ge`: logs failure and continue execution if actual is less than expected.

+/// Checks whether the first argument is greater than or equal to the second
+/// argument.
+///
+/// Evaluates to `Result::Ok(())` if the first argument is greater than or equal
+/// to the second and `Result::Err(TestAssertionFailure)` if it is not. The
+/// caller must then decide how to handle the `Err` variant. It has a few
+/// options:
+///  * Abort the current function with the `?` operator. This requires that the
+///    function return a suitable `Result`.
+///  * Log the test failure and continue by calling the method
+///    `and_log_failure`.
+///
+/// Of course, one can also use all other standard methods on `Result`.
+///
+/// **Invoking this macro by itself does not cause a test failure to be recorded
+/// or output.** The resulting `Result` must be handled as described above to
+/// cause the test to be recorded as a failure.
+///
+/// Example:
+/// ```ignore
+/// use googletest::prelude::*;
+///
+/// #[test]
+/// fn should_fail() -> Result<()> {
+///     verify_ge!(1, 2)
+/// }

+/// Marks test as failed and continues execution if the first argument is
+/// not greater than or equal to the second argument.
+///
+/// This is a **not-fatal** failure. The test continues execution even after the
+/// macro execution.
+///
+/// This can only be invoked inside tests with the
+/// [`googletest::test`][crate::test] attribute. The failure must be generated
+/// in the same thread as that running the test itself.
+///
+/// Example:
+/// ```ignore
+/// use googletest::prelude::*;
+///
+/// #[googletest::test]
+/// fn should_fail() {
+///     expect_ge!(1, 2);
+///     println!("This will print!");

+///```ignore

+/// #[googletest::test]
+/// fn should_fail() {
+///     let argument = "argument"
+///     expect_ge!(1, 2, "custom failure message: {argument}");
