;Procedure:
;  thm_pgs_clean_cmb
;
;
;Purpose:
;  Sanitize combined particle data structures for use with

;  field names conformed to standard.  
;
;
;Input:
;  data: Single combined particle data structure.
;  units: String specifying a units type ('flux', 'eflux', or 'df')
;
;
;Output:
;  output: Sanitized output structure for use within thm_part_products.
