	* src/init.cpp, src/predModule.cpp, src/predModule.h: Finally got a

2011-08-11  Douglas Bates <bates@stat.wisc.edu>

	* src/predModule.cpp: Using solveInPlace to try to avoid memory
	  problems.

2011-07-31  Douglas Bates <bates@stat.wisc.edu>

	* src/lmer.cpp, src/predModule.cpp, src/predModule.h: Trying to track

2011-07-29  Douglas Bates <bates@stat.wisc.edu>

	* src/respModule.cpp, src/respModule.h: Flailing around trying to find

	  getter methods defined in C++ code and reference class. Remove some
	  debugging code.
