Colorbar labeling

Awefully simple code in order to gain some time when trying to label the colorbars.
Works for individual plot or subplots, handles single- and multi-line labels on the top, bottom and/or right of the colorbar.

Input: colorbar handle ([] if unknown), label location ('top', 'bottom' or 'right'), indication for subplots (1 if subplots, 0 otherwise), text label (normal MatLab style)

Output: Nicely postioned labels for the colorbars

Warning: 1) If the label is too close to the colorbar or graph, try reapplying the function, it will largen up the gap

Example: colorbarlabel([],'r',0,[{'String line1'},{'String line2'}])
