Title: Some helper functions for getting cart totals.

Allows you to get the total for a cart (including all recursive items... or not - your decision!)
Allows you to include the tax prices if required (included by default)
Allows you to get only the tax price (including all recursive items... or not - again your decision)

Builds on the pre existing getExtPrice function and adds a new getExtTax function.
