Documentation Improvements

Documentation Improvements:

• Clarify that Sequence can have either finite or infinite length, but FiniteSequence must have a finite length.
• Clarify that Number interface is a reference type.

Release v3

New Features

• Introduce FiniteSequence interface and FiniteNumber concrete type so that the compiler can enforce that a Sequence or Number is of finite length whenever that is expected.
• Some code that would run forever in v2 won't compile in v3.

Breaking Changes

• Number is now an interface instead of a concrete type. Diamond inheritance tree: FiniteSequence and Number implement Sequence. Concrete type FiniteNumber implements FiniteSequence and Number.
• FindAll, FindLast, FindLastN, and FindR now take a FiniteSequence instead of a Sequence

Update README

Update README to show how to use v2.

Docs: No copy or assignment of Number instances

Documentation Fixes

• Explain in more detail how Number instances work.
• Explain that Number instances only support reference type semantics
• Explain that PositionsBuilder objects can't be copied

Documentation Improvements

Documentation Improvements

• Make it clear that Number.WithSignificant, WithStart, and WithEnd return views.

Release v2

Breaking Changes

• Old Number.Iterator() method gone
• Number.IteratorAt() gone
• Number.Reverse() gone
• Number.NumDigits() gone
• Sequence.FullIterator() renamed to Sequence.Iterator()
• Sequence.FullReverse() renamed to Sequence.Reverse()
• Number.FullIterator() renamed to Number.Iterator()
• Number.FullReverse() renamed to Number.Reverse()

Number.WithStart() implementation change

Number.WithStart() implementation change. If Number.IsZero() returns true, Number.WithStart() returns a numberWithStart instance. This is done for consistency so that number.WithStart(5).WithEnd(0) and number.WithEnd(0).WithStart(5) return the same type of value.

Add more tests for FindXXX methods

Code Cleanup

• Add more tests for FindXXX methods.

Expose methods in Sequence interface

New Features

• Introduce End and Ranges methods on Positions type
• Expose Digit type
• Add FullIterator, FullReverse, and WithEnd methods on Number type
• Add FullIterator, FullReverse, WithStart, WithEnd methods to Sequence interface
• Introduce NewNumberFromBigRat function

Introduce FindR

New Features

• Introduce FindR.
