This is a re-write 'from the ground up'. A more 'oject-oriented' approach has been adopted. The 'ten' function/ object has replaced the former 'tne' method. (Motivated in part by the user who commented that "I'm afraid the code in the function '.getTne' appears somewhat cobbled together".)
A number of functions and datasets have been left out temporarily for this release in order to focus on the 'core' package elements. These will be added back in due course, most likely version 0.6.0.

likely be deprecated in due course in favor of
