thanks for your work here, it is very much appreciated!  A faster
assert() will surely help me and others in general, but for my current
application, I think I'll then stick with a local version of assert.m.
I personally usually use assert() only with conditions and maybe with
numerical values, but not the "advanced" versions with structs or
cell-arrays.  Thus I'll use my own, simplified version when speed is
critical as you suggest.

Yours,
Daniel
