Description:
   Fourth-order Runge-Kutta method for solving diff.  eq's in the form of
   y'=f(x,y)  I  wrote  it becouse there were _no_ working R-K around, at
   least I tried several and they were...  at least inacuratte)

Usage:
   Everything  is  plain  simple,  but  anyway...  X0 and Y0 are starting
   values, H is step and M is value for X when calculations will stop.
