Fix two issues in function after_mic_reset.
Create updateContext inside updateParameters instead of having obne per object ... this doesn't change speed at all. Furter, the temporaries could apparently just be created on the stack, without the need for this structure (but this is not yet done).
Add MBase representation of a transpose of a matrix via the wrapper class MatrixTranspose. Needs to be tested, example of use is in GMtest.pl, it just prints out matrix info and the pattern.
