/* Chad's Version of an epic methods ===============================================
* ::SuggestLeapVelocity()
*
* returns a recommended leap velocity vector, given a destination and a leap speed magnitude
* @param outLeapVelocity - out param stuffed with the computed velocity to use
* @param End - desired end point of arc
* @param Start - desired start point of arc
* @param DesiredLeapSpeed - in the magnitude of the leap - assumed to only change due to gravity for the entire lifetime of the projectile
* @param BaseLeapZ - is an additional Z direction force added to the leap (which will not be included in the returned outLeapVelocity) - (defaults to 0)
* @param DesiredZPct (optional) - is the requested pct of the leap in the z direction (0=leap horizontally, 0.5 = leap at 45 degrees).  This is the starting point for finding a leap.  (Defaults to 0.05).
*		the purpose of this is to bias the test in cases where there is more than one solution
* @param CollisionSize (optional) - is the size of bunding box of the leaping actor (defaults to (0,0,0)
* @param TerminalVelocity (optional) - terminal velocity of the projectile
* @param OverrideGravityZ (optional) - gravity inflicted upon the projectile in the z direction
* @param bOnlyTraceUp  (optional) - when TRUE collision checks verifying the arc will only be done along the upward portion of the arc
* @return - TRUE/FALSE depending on whether a valid arc was computed
