   o    Changed kktchk argument maxfn to maximize to agree with 
        optimr and other packages

   o    Streamlined the package to get rid of ufn, ugr, uhess, 
        ugHgenb that are so far unused. 
   o    The optsp environment is only currently used
        with the simple numerical gradient approximations.
   o    kktc renamed to kktchk. scalecheck renamed to scalechk
        for consistency with other naming.

   o    Fixed some elements of manual. Alias optextras-package
        to optextras.

2013-8-20
   o    optsp scratchpad environment added. Note that it
        is aliased in grfwd to avoid a warning in R CMD
        check.

   o    Can change this in numerical derivative routines
        in case of parallel running.

2012-7-18
   o    Extracted helper routines from optplus to 
        create optextras package to put on CRAN.
        Formerly in optplus or optfntools on R-forge,
        but difficulties with dependencies indicated
        that the support routines need to be on CRAN.
        Renamed to avoid name confusion.

2012-7-09
   o    Suppress warnings in ugHgenb -- too much
        unhelpful output
   o    Fixed optansout to print parameters

2012-6-07
   o    Merged optfntools into optplus to ensure 
        R-forge build.

2012-5-26
   o    Added check for "on a bound" in bmchk to aid
	in use of tanh() transformation as in nmkb().
