code: public static String toStringTypes(final Type[] types, final Map<String, Type> generics) {
          return toStringTypes(types, COMMA_SEPARATOR, generics);
      }
docs: Shortcut for {@link #toStringTypes(Type[], String, Map)} with comma separator (most commonly used).
  
  @param types    types to convert to string
  @param generics generics (common for all types)
  @return string with all types divided by comma
  @throws UnknownGenericException when found generic not declared on type (e.g. method generic)
  @see ru.vyarus.java.generics.resolver.util.map.PrintableGenericsMap to print not known generic names
  @see ru.vyarus.java.generics.resolver.util.map.IgnoreGenericsMap to print Object instead of not known generic
  @see EmptyGenericsMap for no-generics case (to avoid creating empty map)
