; PROCEDURE:
;         mms_load_fsm
;
; PURPOSE:
;         Load MMS FSM data
;
; KEYWORDS:
;         trange:       time range of interest [starttime, endtime] with the format
;                       ['YYYY-MM-DD','YYYY-MM-DD'] or to specify more or less than a day
;                       ['YYYY-MM-DD/hh:mm:ss','YYYY-MM-DD/hh:mm:ss']
;         probes:       list of probes, valid values for MMS probes are ['1','2','3','4'].
;                       if no probe is specified the default is probe '1'
;         level:        indicates level of data processing. the default if no level is specified is 'l3'
;         data_rates:   instrument data rate
;         local_data_dir: local directory to store the CDF files
;         source:       sets a different system variable. By default the MMS mission system variable
;                       is !mms
;         tplotnames:   returns a list of the loaded tplot variables
;         get_support_data: when set this routine will load any support data (support data is specified in the CDF file)
;         no_color_setup: don't setup graphics configuration; use this keyword when you're using this load routine from a
;                       terminal without an X server running
;         time_clip:    clip the data to the requested time range; note that if you
;                       do not use this keyword, you may load a longer time range than requested
;         no_update:    use local data only, don't query the SDC for updated files.
;         suffix:       append a suffix to tplot variables names
;         varformat:    should be a string (wildcards accepted) that will match the CDF variables
;                       that should be loaded into tplot variables
;         cdf_filenames:returns the names of the CDF files used when loading the data
;         cdf_version:  specify a specific CDF version # to load (e.g., cdf_version='4.3.0')
;         latest_version: only grab the latest CDF version in the requested time interval
;             (e.g., /latest_version)
;         major_version: only open the latest major CDF version (e.g., X in vX.Y.Z) in the requested time interval
;         min_version:   specify a minimum CDF version # to load
;         spdf:          grab the data from the SPDF instead of the LASP SDC (only works for public access)
;         available:     returns a list of files available at the SDC for the requested parameters
;                        this is useful for finding which files would be downloaded (along with their sizes) if
;                        you didn't specify this keyword (also outputs total download size)
;         versions:      this keyword returns the version #s of the CDF files used when loading the data
;         always_prompt: set this keyword to always prompt for your username and password;
;                        useful if you accidently save an incorrect password, or if your SDC password has changed
;
;
; EXAMPLE:
; 
;
; NOTES:
;     The MMS plug-in in SPEDAS requires IDL 8.4 to access data at the LASP SDC
