Checks

prettycheck includes four main types of functions: test_*(), check_*(), assert_*(), and expect_*(). The test_*() functions return a logical flag; the check_*() functions return TRUE or throw a warning message as a string if the condition is not met; and the assert_*() and expect_*() functions return the input object or throw an error if the condition is not met.
