- Add other std::vector methods like erase(), etc.

- Make memory blocking size flexible, and add related methods like capacity(), reserve(), shrink_to_fit(), etc.
|
||||
- Add non-std methods that are nevertheless needed, e.g. insert(index,val), delete(index), delete(start, end), swap(a_idx,b_idx)
|
||||
- Add a way to change the elements by index, e.g. v[2] = 222; (which is currently NOT supported)
