Users may wish to save long-form combined cluster data as a .csv file
    or similar after combining individual clusters with qm_combine. The qm_verify
    function allows users to import data from any file type readable by R, and verify that it
    has the column names needed for qm_summarize.
qm_verify(clusters)An object created by qm_combine with two or more clusters worth of data
that has been previously saved and requires verification before summarization.
A tibble stored with a custom class of qm_cluster to facilitate data validation.
