writing and comparing doubles with OutputTree and outputtreecompare

I stumbled upon a problem with the outputtreecompare concerning doubles written by an OutputTree. The OutputTree uses ParameterTree::report when writing out the data. The latter adds double quotes around the values (e.g. value = "0.05"). outputtreecompare uses fuzzy_compare_ini to compare these values. The fuzzy compare first tries to convert the values to float, which fails (due to the double quotes). I guess the easiest fix would be to strip the values of quotes in the fuzzy compare before trying the float conversion.
