**     Abstract  :
**          The Ramp Generation Algorithm generates the acceleration ramp.
**          The RampGetValue function computes the next value of acceleration
**          ramp related to the current acceleration ramp direction.

**     Method      :  MC2_rampGetValue (bean MC_Ramp)
**
**     Description :
**         The function performs a linear Ramp generation determined
**         by input parameters.
**     Parameters  :
**         NAME            - DESCRIPTION
**         incrementUp     - Increment up.
**         incrementDown   - Increment down.
**       * p_actualValue   - Pointer to variable
**                           containing actualValue.
**       * p_requestedValue - Pointer to
**                           variable containing requestedValue.
**     Returns     :
**         ---             - If the requestedValue is greater than
**                           actualValue, the rampGetValue function
**                           returns actualValue + incrementUp until
**                           the maximum is reached, (maximum is
**                           requestedValue), at which point it will
**                           return requestedValue. If the
**                           requestedValue is less than actualValue,
**                           the rampGetValue function returns
**                           actualValue - incrementDown until the
**                           minimum is reached, (minimum is
**                           requestedValue), at which point it will
**                           return requestedValue.
