taperNOR 0.2.1

• Use TRUE/FALSE instead of T/F throughout, and stop using T as a variable name in the dlocation() examples (CRAN request).

taperNOR 0.2.0

• kublin_nor() now supports Scots pine in addition to Norway spruce, using a pine-specific Kublin (TapeR) mixed-effects model. Birch is still not fitted and continues to raise an informative error.

taperNOR 0.1.0

• taperNOR(), barkNOR(), and volume() implement the taper, bark thickness, and volume models of Hansen et al. (2023) for Norway spruce, Scots pine, and birch.
• hfromd() and dlocation() invert the taper curve to estimate tree height and diameter at breast height from measured diameters, and to locate the height at which a given diameter occurs.
• kublin_nor() provides the Kublin (2013) mixed-effects taper model via TapeR. The model is currently fitted for spruce only; pine and birch now raise an informative error instead of silently using the spruce model.
• kublin_nor() accepts a vector of diameters in Dx, returning one height per element.
• volume() accepts integer inputs and allows per-tree sp and with_bark, and the h_vol_lower/h_vol_upper clamping no longer affects valid trees.
• Added a Python port of the calculator functions under python/.
