The virtual class CorpusOrSubcorpus is a way to handle corpora specified
by a character vector, region objects, and partition objects
in a uniform manner.
The as.regions-method coerces objects to a regions-object.
The as.data.table method returns the matrix with corpus
positions in the slot cpos as a data.table.
cposa two-column data.table that will include a "cpos_left" and "cpos_right" column
