3// MParList //
4// //
5// This class contains a list of different parameter containers. //
6// //
7// A parameter container is an object which is derived from //
8// MParContainer. //
9// //
10// Normally a parameter container is used for data exchange between two //
11// tasks at runtime. //
12// //
13// You can add every parameter container (Named object) to the //
14// instance and access it from somewhere else via its Name. //
