Detailed Description

Basic structure to be usable with EC methods.

You can inherit your own classes/structures from this or make one with similar members.

The idea is that the EC-versions store the data externally in a map of features that are based on the structure ExternalContainer . The ExternalContainer has certain predefined fields that are used/needed by different methods. Below is a summary of some main methods for reading (r) and writing (w) in the external container.
