Add functionality to store and retrieve the set of 1d nodes used in the tensor product

Add functionality to store and retrieve 1D basis functions of the tensor product

Return 1d nodes as a nested array to match shape expected by modepy

Construct tensor product nodes from 1D nodes in TensorProductElementGroupBase

Remove files created by running pylint

Fix a small typo

Minor change

Get 1D and ND basis by passing a callable to TPGroupBase, probably not final

Change formatting on docstring

Mesh TP element groups: claim to be non-affine by default

Change docstring

Take advantage of changes in modepy to grab 1D components of TP

Add FIXME regarding basis not being a TensorProductBasisObject

Minor changes

Minor documentation change

Remove trailing whitespace

Update handling of non-TensorProductBasis objects in TensorProductElementGroup

Refactor

Minor change

Add type annotations

Stop supplying orth weight to TP basis
