Detailed Description

The ClBackendModelContext is used to pass in CL specific backend ModelOptions.

The supported backend ModelOptions are:

• "FastMathEnabled"
  Using the fast_math flag can lead to performance improvements in fp32 and fp16 layers but may result in
  results with reduced or different precision. The fast_math flag will not have any effect on int8 performance.
• "SaveCachedNetwork"
  Using the save_cached_network flag enables saving the cached network
  to a file given with the cached_network_file_path option.
• "CachedNetworkFilePath"
  If the cached_network_file_path is a valid file and the save_cached_network flag is present
  then the cached network will be saved to the given file.
  If the cached_network_file_path is a valid file and the save_cached_network flag is not present
  then the cached network will be loaded from the given file.
  This will remove the time taken for initial compilation of kernels and speed up the first execution.
