Update LifecycleScopeType.md (#615)

* Update LifecycleScopeType.md

Update the descriptions for the LifecycleScopedRelationship Enumerations.  

Note that this parameterizes historical relationships, like DEV_DEPENDENCY_OF, BUILD_DEPENENCY_OF, RUNTIME_DEPENDENCY_OF, etc. and pelaces them with depends_on with this lifecycleScopeType.

 ## Summary
 
-TODO
+Provide an enumerated set of software lifecycle phases that can provide context to relationships.
 
 ## Description
 
-TODO
+This enumeration summarizes common phases when dependency and other relationships, have different implications, based on their context.  For example,  a build dependency, may have different implications than a runtime dependency.
