Label, PhysDim, Transducer are now cell-strings

[Alois Schlögl <alois.schloegl ***AT***tugraz.at>]

The header structure HDR of BioSig4OctMat has changed.
In the past, the following fields were char-arrays.
	HDR.Label
	HDR.PhysDim
	HDR.Transducer

Now, it is possible to define them as cell-strings (for writing), 
however, char-arrays should also work in future.

The reading mode will return cell-strings are returned. If this is a 
problem in your application, you can convert the cell-strings into 
char-arrays with the command strvcat.


The changes will be in effect in V1.84 and higher.
