Mistakes in ACC documentation and examples

Ardilouze and Lauriane reported these mistakes. Virginie suggests:

var_exp Matrix of experimental anomalies with dimensions: c(nexp, nsdates, nltimes, nlat, nlon) or c(nexp, nsdates, nmembers, nltimes, nlat, nlon) var_obs Matrix of observational anomalies, same dimensions as var_exp except along the first dimension and the second if it corresponds to the member dimension.

acc <- ACC(Mean1Dim(ano_exp, 2),Mean1Dim(ano_obs, 2))
