mcs_Info is a function to show information about the streams that are in a certain file given

as stream, type, n, TimeSpan and infotext.

The output contains the stream name as a eight digits sequence, the type of entity, n is the

number of channels per stream, TimeSpan gives you information about the duration of data

collection and infotext contains optional information about the data type.

mcs_Info uses ns_GetFileInfo to receive the information EntityCount saved in FileInfo.

EntityCount is necessary to call the next function ns_GetEntityInfo and to get EntityLabel

and EntityType as a part of entity. EntityLabel includes some information about the stream

that is connected to EntityType in a structure entities.

The function returns a table with information if the number of output arguments is 0.

Otherwise the information is given as a matrix. That might be helpful if you like to work

on with the given values.
