The MetricsReloaded package under Project-MONAI (https://github.com/Project-MONAI/MetricsReloaded), developed by @csudre, is a recommendation framework for biomedical image analysis validation. As already discussed with @wyli, @Nic-Ma, @csudre and others; being able to use this framework in MONAI would be very valuable. The aim of this issue is to integrate MetricsReloaded support into MONAI.
