	2. map of string - string, where second string is expresion of how should the particles move. This would be a 'bit' more tricky, as string would need to be parsed, constructing correct expression and evaluating it every time, particle needs to be updated.

Another solution would be to pass string to lua code, for dynamic evaluation and getting result, but this would leave particle engine lua-code-dependant, which I do not seek.<br>		2. map of string - string, where second string is expresion of how should the particles move.
