    PURPOSE:
     Reads the omni_config file
    CALLING SEQUENCE:
     cstruct = omni_read_config()
    INPUT:
     none, for the purposes of this example the filename is hardcoded,
     'omni_config.txt',and is put in a folder given by the routine
     istp_config_filedir, that uses the IDL
     routine app_user_dir to create/obtain it: my linux example:
     /disks/ice/home/jimm/.idl/spedas/omni_config-4-linux
    OUTPUT:
     cstruct = a structure with the changeable fields of the !istp
               structure

## OMNI_SOLARWIND_LOAD

[Previous Routine] [Next Routine] [List of Routines]

     Procedure:
      omni_solarwind_load

     Purpose:
      Load solarwind data from OMNI (Pressure and Bz).
      These quantities are used in LMN transformations.

     Keywords:
         trange:     Time range of interest (array with 2 elements, start and end time).
         prefix:     String to append to the beginning of the loaded tplot variable names.
         suffix:     String to append to the end of the loaded tplot variable names.
         hro2:       Flag. Load the newer HRO2 data set instead of HRO.
         res5min:    Flag. If set, it loads 5min data, instead of 1min data.

## OMNI_SOLARWIND_PYTHON_VALIDATE

[Previous Routine] [Next Routine] [List of Routines]

     Procedure:
      omni_solarwind_python_validate

     Purpose:
      Create a savefile with OMNI solar wind variables.
      The savefile can be loaded into Python using PySPEDAS to verify that the Python results match the IDL results.

## OMNI_UI_IMPORT_DATA

[Previous Routine] [Next Routine] [List of Routines]

    NAME:
      omni_ui_import_data

    PURPOSE:
      This routine provides an example for loading data into the GUI from the load
      data panel. The purpose of this routine is to provide a wrapper around the actual
      load data procedure (which is mission specific). This routine handles all the
      'administrative' work of validating times, checking if data exists, and adding the
      data to the GUI's loadedData object. The loadedData object loads and tracks
      all data that is available to the GUI.

## OMNI_UI_LOAD_DATA

[Previous Routine] [Next Routine] [List of Routines]

    NAME:
      omni_ui_load_data

    PURPOSE:
      This routine is an example of how to build a load data panel and handle the
      widget events it produces. This is a template only and creates basic widgets
      that are common to most missions.
      Each mission is different. Some widgets may need to be added to fully specify
      the data set to be loaded or some may not be needed.

## OMNI_WRITE_CONFIG

[Previous Routine] [List of Routines]

    NAME:
     omni_write_config
    PURPOSE:
     Writes the omni_config file
    CALLING SEQUENCE:
     omni_write_config, copy=copy
    INPUT:
     none, the filename is hardcoded, 'omni_config.txt',and is  put in a
     folder given by the routine omni_config_filedir, that uses the IDL
     routine app_user_dir to create/obtain it: my linux example:
     /disks/ice/home/jimm/.idl/spedas/omni_config-4-linux
    OUTPUT:
     the file is written, and a copy of any old file is generated
    KEYWORD:
     copy = if set, the file is read in and a copy with the !stime
            appended is written out
