[OctDev] Optim-1.0.12 fminsearch.m suggestion

[Bob W. <bw...@ro...>]

The fminsearch.m function in the Optim-1.0.12 package is clearly 
designed to implement functionality substantially identical with 
Matlab's fminsearch function.  But Matlab's fminsearch does not have the 
"grad" argument -- I think it is a holdover from an ancient version of 
Matlab when it was called "fmins".  I suggest that argument be removed.  
A diff -c file with proposed changes is attached.
