depeval - check for dependencies

Temporarily removes toolboxes from the matlab path and then executes a
statement. Useful for finding the exact location of dependencies.

SYNTAX:
depeval(evalstring,toolbox1,toolbox2,toolbox3,...)

INPUTS:
evalstring: a string containing a statement to evaluate
toolboxN: a string with the name of the toolbox to remove from the path.

EXAMPLE:
depeval('ezplot(@sin)','images','stats','map'); %test if ezplot(@sin)
works with no access to images,stats, and map toolboxes.

BEWARE: this function temporarily modifies your path. If something fails
you may need to restart matlab.
