PyOTB study

PyOTB add a python layer to the current Python API (OTB 9). It helps to create a more "python style" code, less procedural.

We can take inspiration of this tool to improve existing python API. Before that there are several questions that must be answered:

• What is the state of PyOTB? Code sanity ? Code complexity ? Active repository ?
• What are the code limitation? What can be done in current Python OTB that can not be done in PyOTB ? Can we easily implement the changes ?
• If we want to maintain pyOTB, is the actual maintainer ok with this ?
• How can we integrate this repo in OTB ? Do we have to deprecate our actual Python interface in favor of this one?
