…ion lookup singleton.

Remove contents of referencemodels, but retain tests (forn now).
Package moves to org.openehr to facilitate new RM addition to Archie.
Some class renames for clarity.
Revert change to OpenEhrRmInfoLookup.addTypes()
OpenEhrRmMetaModelsInitialiser.getNativeRms() probably not safe for Android.

Use MetaModels during parsing of CPrimitiveObjects to get access to the correct ModelNamingStrategy. Currently conditional since ADLParser can be created with no MetaModels as well.

In PrimitivesConstraintParser, if the ModelNamingStrategy object can be found, write in the correct RmTypeNames into CPrimitiveObjects (CTerminologyCode and so on).

Rename ArchieModelNamingStrategy to OpenEhrModelNamingStrategy.

Move tests with static dependencies on openEHR RM classes from tools to openehr-rm.
Move or copy other test resources to openehr-rm as needed.
Create tools/src/testFixtures area for test helper classes shared across projects.

…ss CkmRepositoryBuilder in openehr-rm.

Use this for any access to the CKM-mirror copy.

…ument so as to use the correct /resources area.

TODO: there might be a better way to do this, but it seems the safest way to share /resources across projects given the Java model of class loading.

…now take a 'class' arg to ensure the corect /resources area is access (i.e. the caller's area, which could be in the same project or another).

…nd Assert. Not sure if this matters functionally - probably just an efficiency thing.

TODO: check whether this change introduces any errors, or whether it can be reverted by some other simple change.
