[baseTwo]

Work for

• 34 Clean up APIs names and fluent behavior #697

Cleanup Fluent API

• Split out fluent api into a separate namespace for each pipeline component
  
• Separate the "worker" class from the "fluent" class and extensions:

  	CQL to ELM Translation	ELM to Assembly Compilation	Library Invocation
  Worker class:	CqlToElmTranslator	ElmToAssemblyCompiler	LibrarySetInvokerBuilder LibrarySetInvoker LibraryInvoker DefinitionInvoker
  Worker config:	CqlToElmTranslatorConfig	ElmToAssemblyCompilerConfig	n/a
  Fluent toolkit:	CqlFluentToolkit	ElmFluentToolkit	FluentInvocationToolkit

Other

• Rename project API to CqlApiExamples
• Rename classAssemblyData to AssemblyBinary (since Data doesn't pluralize well)
  • Also AssemblyDataExtensions, AssemblyDataWithSourceCode
• Make fields Services and Logger private on class CqlToElmConverter in existing SDK
• Remove exception logging for GetBuilder in class CqlToElmConverter in existing SDK (this will be handled higher up in CqlToElmTranslator`)
• Had to make early changes to ResourcePackager to work on in-memory objects for cql, elm, etc, and not just directories. Needed this for another project. Also in preparation for next issue
• Documentation on public types

Integration TestRunner

• Copied the CMS Measures dlls into the IntegrationRunner repo. (Later this will be changed to the FHIR library resources)
• Use the new Invocation toolkit to run IntegrationRunner tests PR 31 in Firely.Cql.Sdk.Integration.Runner
