Many functions in this package relies on the usage of unique haplotypes due to
known issues when using identical or duplicated sequences for species delimitation analysis.
Thus, these outputs will very often refer only to unique haplotypes within a given dataset,
which can be determined by using functions like hap_collapse. Assuming that a
duplicated or identical sequence should share the same properties as the first
sequence of the group has, hap_unite() combines the output of haplotype_tbl
with the output of delim_join. Alternativelly, one may use collapse_others and
delim_consensus as well. This output may be used for downstream analysis or
to determine in which cluster a given sequence belongs.
