System trait

You can implement one of those processes, but if you implement process_all - only it will be called, and if you dont implement process_all - all process_* will be called.

Most common case - implement only process_one.

Required Methods

System will subscribe only on components, sutisfied by this aspect.

Provided Methods

For each returned aspect, one additional entity pack DataList will be received. Strongly recomends use it only with registration macro.
