v3.0.13
Changes copyright dates on the code
Added support to run unit tests in a multithreaded context - This is controlled by specifying the 'mtstress' argument when running `unit_test`. - The goal is to detect if the operator/transformation fails in this context. - In this mode, the test will be executed 5'000 times in 50 threads concurrently. - Allocation & initialization of the operator/transformation is performed once in the main thread, while the evaluation is executed in the threads. - This is consistent with the library's support for multithreading, where initialization and loading of rules is expected to run once. See issue #3215.
