Vector: Copy arrays in a sane way for non-trivially copyable types

Browse Source 
Avoids this type of compilation warnings:
‘void* memcpy(void*, const void*, size_t)’ writing to an object of non-trivially copyable type ‘class Complex<float>’; use copy-assignment or copy-initialization instead [-Werror=class-memaccess]
