in cakephp 2 when need vendor or related class loaded globally, adding require or app use inside bootstrap.php ot core php.

in cakephp 3 should require vendor files ? dont want declare vendor require in every class , template file use vendor files.

vendor files 3rdparty files. custom static utility classes not vendor files rather app files. can put them under src/lib/. ensure use proper namespace classes , add proper use statement wherever need use class.

for e.g. if lib class src/lib/foobar.php should have classname app\lib , "use" statement use app\lib\foobar.
