This class tries to extract properties from the User-Agent string itself. This is a completely separate step to the main JSON tree walk but uses the results of the tree walk to optimise the property extraction. The property extraction is done in two steps.

Step 1: Try and identify the type of User-Agent and thus the set of property extraction rules to run. This is optimised by the properties from the tree walk.

Step 2: Run the rules found in step 1 to try and extract the properties.
