include online DMD, window DMD #5

The online stuff looks great, but please don't reorganize the other files (e.g., streaming, tdmd), at least as a part of this same pull request. Just add online and window for now, and then we can discuss rearranging later if we want. |

I have switched back to the original folder structure, and updated the readme file. Online and window implementation are added. |

You are computing P*x four times here; better to compute it once and save it: Px = obj.P * x and then use this in the definition of gamma, and in the updates for obj.A and obj.P. Of course, P is symmetric, so x'*obj.P is the same as Px'

I have updated the matlab implementation. Now both matlab and python implementation are more efficient, matrix vector multiplication is computed beforehand.
