Detailed Description
       The FTP Throughput Performance plugin allows the user to obtain calculated performance information for all types of transfers except a
       third party transfer in which Extended Block mode is not enabled.

       Note: Since this plugin is built on top of the Performance Marker Plugin, it is not possible to associate both plugins with a handle

Typedef Documentation
   typedef void(* globus_ftp_client_throughput_plugin_begin_cb_t)(void *user_specific, globus_ftp_client_handle_t *handle, const char *source_url,
       const char *dest_url)
       Transfer begin callback

       This callback will be called when a transfer begins. Parameters:
	   handle The client handle associated with this transfer
	   user_specific User argument passed to globus_ftp_client_throughput_plugin_init
	   source_url source of the transfer (GLOBUS_NULL if 'put')
	   dest_url dest of the transfer (GLOBUS_NULL if 'get')

       Returns:

	   o n/a

   typedef void(* globus_ftp_client_throughput_plugin_stripe_cb_t)(void *user_specific, globus_ftp_client_handle_t *handle, int stripe_ndx,
       globus_off_t bytes, float instantaneous_throughput, float avg_throughput)
       Stripe performace throughput callback

       This callback will be called with every performance callback that is received by the perf plugin. The first callback for each stripe_ndx
       will have an instantaneous_throughput based from the time the command was sent.

       Parameters:
	   handle The client handle associated with this transfer
	   user_specific User argument passed to globus_ftp_client_throughput_plugin_init
	   bytes The total number of bytes received on this stripe
	   instantaneous_throughput Instanteous throughput on this stripe (bytes / sec)
	   avg_throughput Average throughput on this stripe (bytes / sec)
	   stripe_ndx This stripe's index

   typedef void(* globus_ftp_client_throughput_plugin_total_cb_t)(void *user_specific, globus_ftp_client_handle_t *handle, globus_off_t bytes,
       float instantaneous_throughput, float avg_throughput)
       Total performace throughput callback

       This callback will be called with every performance callback that is received by the perf plugin. The first callback for will have an
       instantaneous_throughput based from the time the command was sent. This callback will be called after the per_stripe_cb

       Parameters:
	   handle The client handle associated with this transfer
	   user_specific User argument passed to globus_ftp_client_throughput_plugin_init
	   bytes The total number of bytes received on all stripes
	   instantaneous_throughput Total instanteous throughput on all stripes (bytes / sec)
	   avg_throughput Average total throughput on all stripes (bytes / sec)

   typedef void(* globus_ftp_client_throughput_plugin_complete_cb_t)(void *user_specific, globus_ftp_client_handle_t *handle, globus_bool_t
       success)
       Transfer complete callback

       This callback will be called upon transfer completion (successful or otherwise) Parameters:
	   handle The client handle associated with this transfer
	   user_specific User argument passed to globus_ftp_client_throughput_plugin_init
	   success indicates whether this transfer completed successfully or was interrupted (by error or abort)

       Returns:

	   o n/a

   typedef void*(* globus_ftp_client_throughput_plugin_user_copy_cb_t)(void *user_specific)
       Copy constructor

       This callback will be called when a copy of this plugin is made, it is intended to allow initialization of a new user_specific data.
       Parameters:
	   user_specific this is user specific data either created by this copy method, or the value passed to init

       Returns:

	   o a pointer to a user specific piece of data

	   o GLOBUS_NULL (does not indicate error)

   typedef void(* globus_ftp_client_throughput_plugin_user_destroy_cb_t)(void *user_specific)
       Destructor

       This callback will be called when a copy of this plugin is destroyed, it is intended to allow the user to free up any memory associated
       with the user specific data. Parameters:
	   user_specific this is user specific data created by the copy method

       Returns:

	   o n/a

   globus_result_t globus_ftp_client_throughput_plugin_init (globus_ftp_client_plugin_t *plugin,
       globus_ftp_client_throughput_plugin_begin_cb_tbegin_cb, globus_ftp_client_throughput_plugin_stripe_cb_tper_stripe_cb,
       globus_ftp_client_throughput_plugin_total_cb_ttotal_cb, globus_ftp_client_throughput_plugin_complete_cb_tcomplete_cb, void *user_specific)
       Throughput plugin init

       Use this function to initialize a throughput plugin. The throughput plugin sits on top of the perf_plugin. The only required param is
       'plugin', all others may be GLOBUS_NULL

       Parameters:
	   plugin a pointer to a plugin type to be initialized
	   begin_cb the callback to be called upon the start of a transfer
	   per_stripe_cb the callback to be called every time updated throughput info is available for a given stripe
	   total_cb the callback to be called every time updated throughput info is available for any stripe
	   complete_cb the callback to be called to indicate transfer completion
	   user_specific a pointer to some user specific data that will be provided to all callbacks

       Returns:

	   o GLOBUS_SUCCESS

	   o Error on NULL plugin

	   o Error on init perf plugin

   globus_result_t globus_ftp_client_throughput_plugin_set_copy_destroy (globus_ftp_client_plugin_t *plugin,
       globus_ftp_client_throughput_plugin_user_copy_cb_tcopy_cb, globus_ftp_client_throughput_plugin_user_destroy_cb_tdestroy_cb)
       Set user copy and destroy callbacks

       Use this to have the plugin make callbacks any time a copy of this plugin is being made. This will allow the user to keep state for
       different handles.

       Parameters:
	   plugin plugin previously initialized with init (above)
	   copy_cb func to be called when a copy is needed
	   destroy_cb func to be called when a copy is to be destroyed

       Returns:

	   o Error on NULL arguments

	   o GLOBUS_SUCCESS

   globus_result_t globus_ftp_client_throughput_plugin_destroy (globus_ftp_client_plugin_t *plugin)
       Destroy throughput plugin

       Frees up memory associated with plugin. Parameters:
	   plugin plugin previously initialized with init (above)

       Returns:

	   o GLOBUS_SUCCESS

	   o Error on NULL plugin

   globus_result_t globus_ftp_client_throughput_plugin_get_user_specific (globus_ftp_client_plugin_t *plugin, void **user_specific)
       Retrieve user specific pointer. Parameters:
	   plugin plugin previously initialized with init (above)
	   user_specific pointer to storage for user_specific pointer

       Returns:

	   o GLOBUS_SUCCESS

	   o Error on NULL plugin

	   o Error on NULL user_specific
