Description: this set of functions can be used in sequence (or in separate) to draw an automatic SVG Graphic given any x/y set of point in two separate vectors
first use DualVectorSort to sort the values, then use RemoveRepeatedValues to remove the repeated points.
After this use OptimalDisplayFromVectors for obtaining the optimal zoom parameters for GetGraphSVG, wich writes a FString containing SVG code for the grafic
reminder: there is no < and > at the begining and by the end on the code becaus it is intended to be used in a ::ProcessHttpMessage(HttpStream &hStream) with hmStream.SSPrintf(HtmlTagStreamMode, temp_string_1.Buffer()); that contains the <> tags
