;Name: thm_esa_specmom_calc.pro
;Purpose: This is a wrapper routine for getting some ESA L2 data quanitities.
;Inputs:  DATE: The date (ie, '2007-07-01')
;         DUR: The duration in days.
;         SC: The spacecraft  (ie, 'a b c d e')
;         MTYPE: Moments type (ie, 'spectrogram density velocity temperature')
;         SPECIES: Ions or electrons
;         DISTRIBUTION_TYPE: Full, reduced or burst
;Output:  Tplot variables are created in the IDL environment.
;Caveats: Reduced moment calculations don't work very well yet.
