//
//          Version 1.0
//            by
//          Tobias Stockmanns
//  Seperates an input string into substrings and stores them in a
//  string vector. The seperation criteria is a string of characters.
//  If no delimiters are given the default delimiter " " is used.
//
//  Example:
//    std::vector<std::string> Output
//    TPndStringVector Input("Column:Row Type: Test ", ": ");
//    Output = Input.GetStringVector();
//
//    Output[0] = "Column"
//    Output[1] = "Row"
//    Output[2] = "Type"
//    Output[3] = "Test"
