Detailed Description
Configuration element - represents (sub)tree of ARC XML configuration.
This class is intended to be used to pass configuration details to various parts of HED and external modules. Currently it's just a wrapper over XML tree. But that may change in the future, although the interface should be preserved. Currently it is capable of loading an XML configuration document from a file. In future it will be capable of loading a more user-readable format and processing it into a tree-like structure convenient for machine processing (XML-like). So far there are no schema and/or namespaces assigned.
