Variable renaming

This wiki contains all the function parameter name changes/cleanup for POT 1.0

------------------documentation/examples------------------

• n -> n_source_samples

• xs/xt -> x_source/x_target

• G0/Gs -> Gamma_emd/ Gamma_sinkhorn (May be ?)

• reg parameter entropic -> epsilon (blur ?)

• d (dimension parameter) -> n_features

• N (barycenter example) -> N_distributions

X1 -> X_source (color transfer)

------------------variable names------------------

numItermax -> maxiter

numInnerItermax -> maxiter_inner

stopThr -> stop_threshold

(reg -> blur ?)

log (variable not bool) -> log_{namefunction}

numIterMax -> maxiter (scikit-learn compatible)
