I created a directory "gpfa_elephant" and copied all Python codes in it.
We should do all elephantification works only in this directory and keep the codes under "gpfa_v0203" intact.

@Junji110 Actually a new branch would be better to work on this issue. Also it would be nice to have both versions available as fallback alternatives.

I created the branch gpfa_elephant. Please use this branch for further elephant developments.

I think, at least for the moment, we should have the two versions in a same branch so that we can easily check the results of the two versions during the development.
If they are in separate branches, we need to go back and forth between the brunches every time we want to check the consistency between the two versions, which I think quite cumbersome.

For implementing the unittests we will move the branch to inm-6 github
