misc.constructorOf: call a classes constructor, without knowing in advance which constructor to call.

misc.ss some more functions that are useful for state space model based simulations, especially for large coupled systems.

misc.ss.add2signalName: general function to add strings to InputName or OutputName of state-space-models ss()

quantity.Discrete: mtimes now uses transpose instead of ctranspose, and transposing is hidden in the names

misc.invertBacksteppingKernel: now the successive approximation is implemented locally in the function instead of using code that is not part of the library

- setName() for setting names of all elements of a quantity array
- transpose() for transposing quantities: now call by value and change of name
- flipGrid() changes name now

misc.ss.combineInputSignals: new function to automatically combine input signals that suite to the input names of a state space.

misc.Gain(s): added inputType2sumblk() to ease creation of sumblk() with the Control Systems Toolbox, be creating a string [inputType(1) + inputType(2) + ... inputType(end)]

- moved finiteDifferenceStencilBoundary to numeric.fd.stencilBoundary
- added numeric.fd.matrix: implemented five point central finite differences scheme for 1st and 2nd order derivatives
- unittests for both

numeric.finiteDifferenceStencilBoundary.m new function to calculate finite difference approximations at boundaries
