Builds an object of class foldert
from a 3d
array.
## S3 method for class 'array'
as.foldert(x, ind = 1, var = 2, time = 3, ...)
x 
a 
ind, var, time 
three distinct integers among 1, 2 and 3.

... 
further arguments passed to or from other methods. 
an object ft
of class foldert
that is a list of data frames, each of them corresponding to a time of observation; these data frames have the same column names.
