Documentation update

This DF is used to combine/connect multiple physical lanes (i.e. within intersections or road

 segments). For signalized movements, the **connectsTo** data frame defines e.g. the relation between

 ingress and egress lanes within an intersection. It describes the allowed manoeuvres and includes the

 link (**signalGroup** identifier) between the [**MapData**](#MapData) and the [**PAT**](#PAT) message. The data frame is also used

 link (**signalGroup** identifier) between the [**MapData**](#MapData) and the [**SPAT**](#SPAT) message. The data frame is also used

 to describe the relation of lanes within a non signalized intersection (e.g. ingress lanes which are

 bypassing the conflict area and ending in an egress lane without signalization). Within a road segment,

 it is used to combine two or multiple physical lanes into a single lane object.

 index for fragmentation of large [**MapData**](#MapData) descriptions. The fragmentation of the messages shall be

 executed on application layer. The fragmentation occurs on an approach base. This means that almost a

 complete approach (e.g. lanes, connectsTo, etc.) has to be included within a fragment.

 The decimal value of the `layerID` is used to define the amount of maximum [**MapData**](#MapData) fragments. The

 The decimal value of the **layerID** is used to define the amount of maximum [**MapData**](#MapData) fragments. The

 lower value defines the actual fragment.
