#10946: Add dt to system arguments

 Reporter:  ilja.j.honkonen@…  |      Owner:  karsten
     Type:  Feature Requests   |     Status:  new
Milestone:  To Be Determined   |  Component:  odeint
  Version:  Boost 1.57.0       |   Severity:  Problem
 Keywords:                     |
-------------------------------+---------------------
 A popular algorithm for calculating the change in velocity of a charged
 particle in a magnetic field (1) requires the length of the time step
 while integrating (dx/dt := f(x,t,dt)) and cannot be used with odeint as
 far as I could tell so I suggest modifying the definition of system from
 sys( x , dxdt , t ) to sys( x , dxdt , t , dt ). Some enable_if magic
 should allow all existing code using the current API to work.
