#151 Python - access to predefined color scales via constant

[Benjamin]

It would be great to have access to color scales in a similar way we access predefined colors such as tlp.Color.Amber, for example we could propose tlp.ColorScale.colorbrewer_RdYlGn_10.

Referring to this discussion: https://sourceforge.net/p/auber/discussion/206283/thread/950786e1/?limit=25#b500

Thanks for your suggestion.
The ColorScaleManager class has been recently added by Antoine in the current svn code line (commit #11504).
So predefined color scales can now be accessed using a call such as
tlpgui.ColorScaleManager.getColorScale("RdYlGn_10")
