Added tests (on the service and host side) and began on service
Setup testing
Converting sat to correct outline class and testing
Deleted leftover services_common.dart in lib.  Moved ServiceActionEvent from utils to services/services_common.dart (exported by services).  Added "as analyzer" to analyzer.dart and removed "as common" from services_common import to make services_common classes first-class and shadowed analyzer classes second-class.
Full (basic) implementation of outline with methods, variables, top-level variables and functions.  Added tests for current implementation.  Still need to implement modifiers
Added todos for modifiers and types.  Cleaned up (removed unused test)
Removed all testing
Resolved conflicts
Changed print to throwing UnimplementedError
Review fixes
