/**
  @file
  @brief Returns a dataset with all Stored Processes, or just those in a
    particular folder / with a  particular name.
  @details Leave blank to get all stps.  Provide a Tree (path or uri) or a
    name (not case sensitive) to filter that way also.
  usage:

      %mm_getstps()

      %mm_getstps(name=My STP)

      %mm_getstps(tree=/My Folder/My STPs)

      %mm_getstps(tree=/My Folder/My STPs, name=My STP)

  <h4> Dependencies </h4>
  @li mm_gettree.sas

  @param tree= the metadata folder location in which to search.  Leave blank
    for all folders.  Does not search subdirectories.
  @param name= Provide the name of an STP to search for just that one.  Can
    combine with the <code>tree=</code> parameter.
  @param outds= the dataset to create that contains the list of stps.
  @param mDebug= set to 1 to show debug messages in the log
  @showDesc= provide a non blank value to return stored process descriptions
  @showUsageVersion= provide a non blank value to return the UsageVersion.  This
    is either 1000000 (type 1, 9.2) or 2000000 (type2, 9.3 onwards).

  @returns outds  dataset containing the following columns
   - stpuri
   - stpname
   - treeuri
   - stpdesc (if requested)
   - usageversion (if requested)

  @version 9.2
