#21 Using labels throughout Wiki

[Burkhard Schmidt]

Adding labels to the demo examples' Wiki pages indicating e.g. the different numerical techniques used there (such as Chebychev, Strang splitting, LZ surface hopping etc). Those labels can then be referenced within the Wiki pages describing those numerical techniques.

Similar labeling also for the different plot styles (such as contour, polar, reduced_1d|2d etc). Those labels can then be referenced within the Wiki pages of the Matlab project describing those visualization techniques.
