Add description for identification related knowledge sources

[hagenw]

I guess the current entry for the identifaction related knowledge sources is outdated: http://docs.twoears.eu/en/latest/blackboard/knowledge-sources/identification/

@kashefy, @ivo--t could you please update it by creating a pull request. As far as I see the following knowledge sources are involved, correct?

AbstractAMLTTPKS
CollectSegmentIdentityKS
IdDecisionKS
IdTruthPlotKS
IdentityKS
IdentityLocationDecisionKS
IdentityLocationKS
IntegrateFullstreamIdentitiesKS
IntegrateSegregatedIdentitiesKS
SegmentIdentityKS
SegmentationKS
StreamSegregationKS

It could of course be that the current subsection in the documentation are not fitting with the new structure of knowledge sources. If this is the case we should also briefly discuss this here, and change it accordingly.

Please see my comment in #51 .
A (unfinished) branch for documentation of AMLTTP has already been created by @kashefy , although for some reason I can't see it at the moment -- have you pushed, @kashefy ?

[kashefy]

I've pushed the branch for the AMLTTP documentation. Look for amlttp_skeleton

[hagenw]

OK, thanks.
Then for the knowledge sources the following remain for updates in the knowledge source part of the documentation:

AbstractAMLTTPKS
CollectSegmentIdentityKS
IdDecisionKS
IdTruthPlotKS
IdentityLocationDecisionKS
IdentityLocationKS
IntegrateFullstreamIdentitiesKS
IntegrateSegregatedIdentitiesKS
SegmentIdentityKS
IdentityKS
