% STK_OPTIM_ISAVAILABLE checks if a given optimizer is available
%
% CALL: B = stk_optim_isavailable (ALGO)
%
% return true is ALGO is available, and false otherwise. ALGO can be the
% short name of an algorithm (such as 'octavesqp'), the corresponding class
% name (such as 'stk_optim_octavesqp'), a handle on the class constructor
% (such as @stk_optim_octavesqp) or an algorithm object.
