[IGSTK-Users] Landmark3DRegistration::computeRMSError()

[Luis Ibanez]

Hi Torleif

The method that computes the RMS error must not be in the public API
because the are conditions that must be statisfied before the
computation can be performed. A premature attempt to compute and RMS
error will result in a bogus numerical result. Only the state machine
can determine when the appropriate conditions for computing the RMS
are met.

However, once the computation is performed, we should offer a public
method "RequestGetRMS", that will send the RMS value on a Event with
payload.

As you pointed out, that extra method "RequestGetRMS()" should follow
the Request/Observer pattern.
