Detailed Description

Helper findlet for performing an extrapolation of a mSoP of one plane to another plane using the representation stored in the mSoP.

Will return the travelled distance or NAN, if

• the extrapolation failed or
• the extrapolation was into another direction as the direction parameter. See below.
