clamp inverse link function (issue #179)
comment-out inverse link clamp (#179)
utility function for trying out various optimizers
address #195: docs match code on options(lmerControl=...)
warn on bogus global control options

closes #195
also add some check.conv.grad="ignore" to test-lmer.R for reltol
drop asOneSidedFormula in subset printing for summary

closes #163
fix but in tests/priorWeights.R.  mlmRev is only suggested and so certain tests should only be run if mlmRev is available
version bump
more checks for mlmRev in tests
better pointers to the  'plots.thpr.Rd'  help page
optwrap() , adj=TRUE, "Nelder_Mead":  fix 'xst' logic
  {{ and where did BB get magic factor 0.2 from ?}}
- new logProf() which allows to have  log(sigma) and sigma01 (*non*-logged)
  via ranef=FALSE
- eliminate not-exported  varpr() which will be an accidental duplication
  of varianceProf()
- fix varianceProf() to keep the fixed effects {as log(<profile) does}, but
  does adapt the column names of transformed; also allows ranef;
- stripExpr() adapted to work with varianceProf() result
also 40164ff : + logProf
keep 'method' for "optimx"
first step to not only *fit* with many methods, but then also be able to
profile() with that optimizer setup
change from absolute to relative gradient testing
indentation *only*
