The calculation of effective degrees of freedom has been improved. In previous versions, in a multi-step calculation, the effective degree of freedom were calculated at each step based on the degrees of freedom calculated for the previous step (using a modified Welch-Satterthwaite approximation). Now effective degrees of freedom are alway calculated directly from the independent variables using the Welch-Satterthwaite equation.
CODATA 2022 values instead of 2018 values are used in the Constants module.
The significance value in budget table has been redefined from (sensitivity coefficient * standard uncertainty/combined uncertainty) to the square of that value so that the significance value sum to one.
Units can now be raised to a fractional power and many other bug fixes.

A constant library has been added with physical constants that can be accessed by name or alias with the constant function. The search_constants function with no argument gives a listing of all built-in constants. Each constant definition includes any correlations with other constants.
The Quantity class has been added to represent a general numerical value multiplied by a unit and the unit function has been added to retrieve Unit instances from the unit library by name or alias. Unit instances can now be multiplied and divided by other Unit instances to produce composite units, can be multiplied and divided by numbers to produce Quantity instances or multiply or divide Quantity instances. The gummy class is now a subclass of Quantity with a nummy value rather than a subclass of nummy. A QuantityArray class has been introduced to represent an array of values all with the same unit. Multiplying a Unit instance by a list, tuple, or numpy array produces a QuantityArray instance.
The immy class has been introduced as an ummy valued counterpart of the jummy class for representing complex values with uncertainties. immy and jummy values can now be displayed in a polar representation in addition to a cartesian representation. immy and jummy .r and .phi properties have been added to access the magnitude and argument of the values as a complement to the .real and .imag properties.
