Get Number of Tokens.
The method will get the number of tokens in a corpus or partition, or the dispersion across one or more s-attributes.

One or more s-attributes can be provided to get the dispersion of tokens across one or more dimensions. Two or more s-attributes can lead to reasonable results only if the corpus XML is flat.
The size-method for features objects will return a
named list with the size of the corpus of interest ("coi"), i.e. the number
of tokens in the window, and the reference corpus ("ref"), i.e. the number
of tokens that are not matched by the query and that are outside the
window.
If .Object is a corpus (a corpus object or specified by
corpus id), an integer vector if argument s_attribute is
NULL, a two-column data.table otherwise (first column is the
s-attribute, second column: "size"). If .Object is a
subcorpus_bundle or a partition_bundle, a data.table
(with columns "name" and "size").
See dispersion-method for counts of hits. The hits
method calls the size-method to get sizes of subcorpora.
