number_line objects as criteria in record_group

[OlisaNsonwu]

in v0.0.1, to use a \code{number_line} objects as a \code{criteria}, a dummy \code{criteria} was needed and the \code{number_line} values used as sub_criteria instead.
This step now is no longer required for users. It's done automatically by the record_group() i.e.

Old requirement:
dob$dum_var <- 1
dob$pids_b <- record_group(dob, criteria = dum_var, sub_criteria = list(s1a="range"))

New way:
dob$pids_c <- record_group(dob, criteria = range)

pids_b will be equal to pids_c

Updated in v0.0.1.9000 (v0.0.2)
