class RooWorkspace::CodeRepo: public TObject

 Import code of class 'tc' into the repository. If code is already in repository it is only imported
 again if doReplace is false. The names and location of the source files is determined from the information
 in TClass. If no location is found in the TClass information, the files are searched in the workspace
 search path, defined by addClassDeclImportDir() and addClassImplImportDir() for declaration and implementation
 files respectively. If files cannot be found, abort with error status, otherwise update the internal
 class-to-file map and import the contents of the files, if they are not imported yet.

 Custom streamer for the workspace. Stream contents of workspace
 and code repository. When reading, read code repository first
 and compile missing classes before proceeding with streaming
 of workspace contents to avoid errors.

 Return STL string with last of class names contained in the code repository

 For all classes in the workspace for which no class definition is
 found in the ROOT class table extract source code stored in code
 repository into temporary directory set by
 setClassFileExportDir(), compile classes and link them with
 current ROOT session. If a compilation error occurs print
 instructions for user how to fix errors and recover workspace and
 abort import procedure.
