Lemur 1.1 release notes

• Makefiles updated to support single application linkage
• Configure script updated to support debug or optimized compilations, using --with-comp-mode
• ReutersParser class added
• New application RelFBEval added
• GenerateQueryModel extended to load/save query model
• Error reporting added to applications, exits after bad parameters
• More examples provided in data directory for relevance feedback
• FUtil class added in utility, fileExist() moved here from BasicIndex
• PushIndexer modified to accept new parameter dataFiles
• Bugs Fixed:
  1. Problem: Windows (without service packs installed) lemur_utility.mak has ambiguous operator compilation error in String.cpp
     Solution: line 19 String tmp, should be type (lower-case) string
  2. Problem: .dtlookup file has not been flushed properly by InvFPPushIndex if read before the build process exits
     Solution: in InvFPPushIndex.cpp, close .dtlookup file in destructor
  3. Problem: InvFPIndexMerge does not do hierarchical merge properly with gcc-3.0.1
     Solution: change iter = iter++; statements to iter++;
  4. Problem: purify reports possible UMR
     Solution: in InvFPTextHandler.cpp, remove redundant declaration of variable "first" in constructor
  5. Problem: feedback applications do not work on Windows , dynamic_cast unpredictable behavior compilation warnings
     Solution: in various retrieval classes, change dynamic_cast to C-style cast on Windows
     ** this fix was undone in version 1.9.2. windows makefiles changed to allow type checking during runtime.
  6. Problem: applications core dump when parameter files are ill-formed
     Solution: modify error.c to exit after error occurs
  7. Problem: get method in RetParamManager.hpp caused multiply defined linkage problem when included by non-application files
     Solution: define get method as static
