method to get string from theme color Type

[Regina Henschel]

Hi Thomaž,

for my current work on exporting Fontwork shapes to docx I need for a 
theme color the string used in OOXML markup. Does already a method 
exist, that takes the Type of a theme color and returns that string? I 
could not find one.

With Type I mean the value returned by getType() of XThemeColor or 
CharColorTheme or FillColorTheme.

I'm looking for a method like: getMarkupStringForThemeColorType(3) with 
result "tx2".

If it doesn't exist, shall I define one local in my FontworkHelpers only 
for me, or do you want to have such method somewhere else?

If latter, please suggest a location and a name.

Kind regards,
Regina
