OpenSIMPLY components

OpenSIMPLY consists of components that can be used seperately.

Simply Memory Manager

Starting with version 2.1.9, the OpenSIMPLY package contains a Simply Memory Manager (SMM). It replaces the Free Pascal native memory manager on Windows and works correctly with Lazarus. SMM implements the handling of low memory critical cases and doesn't hang on multiple big memory allocation. Simply Memory Manager demonstrates good performance both for single- and multi-thread tasks.
