Marking addressee and excluding from MLU counts

Caro,

	MLU is supposed to be used with %mor tier. If you are running MLU on just speaker tier, then you will get fewer morpheme counts than if you had %mor tiers in the file, because morphemes are identified by special symbols on %mor tier only. I will change MLU to not ignore [+ mlue] post-code when running MLU on speaker tier.

For example, instead of %add: SIB dependent tier specify post-code [+ sib] on the main speaker tier. If you want to always exclude utterance from MLU, then specify post-code [+ mlue]. The advantage of using this post-code is that it will effect results of MLU, KIDEVAL and few other CLAN commands automatically without you having to specify anything on the command line. If you choose to use your own post-code, then on command line you need to add option -s"[+ sib]" to exclude utterances with that post-code from any CLAN analyses.

This is because sometimes we will want a measure of how much CDS a particular adult is using (no matter the addressee) and sometimes we will want a measure of how much CDS is addressed to a particular target_child.
