0.1.0

New Features

• multivectors.xy and from multivectors import xyz are now a thing (swizzling on the module level) but unlike class-level swizzling, invalid chars will cause an AttributeError (from multivectors import a would set a to 1.0 otherwise)
• Blade.terms returns (blade,) for compatibility with MultiVector.terms
• real @ blade is now supported
• A ** -n = 1 / (A ** n)
• real ^ blade is now supported
• To better mimic regular floats, scalar blades can now be passed to complex(), int(), and arr[]
• round(blade), math.trunc(blade), math.floor(blade), and math.ceil(blade) act on the scalar part, returning that times the bases
• simple @ multivector is now supported
• simple ^ multivector is now supported
• round(multivector), math.trunc(multivector), math.floor(multivector), and math.ceil(multivector) act on each component of the multivector, returning their sum

Changes

• names_to_idxs() takes a new parameter that controls whether to fail on invalid chars
• repr(Blade) uses repr() on its scalar again; %.2f is still used in str()
• multivector ** -n is now explicitly rejected

Fixes

• names_to_idxs() no longer fails on invalid chars between e and the digits of the number (enables e_1)
• idxs_to_idxs() now always returns a list
• str(Blade) used to return e0 for e1
• blade @ non-simple now correctly fails
• Fixed infinite recursion when Blade(scalar=x) / blade
• blade ^ non-simple now correctly fails
• blade ^ real no longer fails
• Correction: abs(blade) is (blade * blade) ** .5, not blade.scalar
• float(blade) can't return NotImplemented, so raise TypeError
• multivector % grade now returns the blades, not just their scalars
• MultiVector.angle_to() returns a real, not a MultiVector.
• Noted in docstring of MultiVector.angle_to() that multivectors of singular grade 1 only are accepted
