You can switch the command line in Shogun Post between HSL and Python.

The Python command line is essentially a mini script editor, not a direct interface to a Python interpreter, so variables will not persist from one call to the next. However, you don't need to create a client object when using the Shogun Post command line: default clients for the two Python modules are always available: `shogunPost` for the ViconShogunPost module, and `sdk` for the ViconShogunPostSDK module:

- `shogunPost.Command()` This is the ViconShogunPost module, which is the simple Vicon SDK.
- `sdk.Command()` This isthe ViconShogunPostSDK module, which is the expandedShogun Post-specific SDK.
