%
% Function to search for executable. If the executable isn't found
% in searchpath, look in environment search path.
%
% parameter:
% name: name of the binary to search
% searchpath: (list of) search paths
% err_fail: 0/1, throw an error if binary is not found (default is 1)
%
% Output:
% binary_location:
% if found in searchpath: full path of binary
% if found in environment search path: name of binary
% if not found: empty string
