This defines a right ideal in a noncommutative ring. Not much can be done with these objects at this point (as one can tell by the dearth of operations that take an NCRightIdeal as input), , but eventually it will be a 'fully featured' object.

Methods that use an object of class NCRightIdeal :

basis(ZZ,NCRightIdeal) -- Returns a basis of an NCRightIdeal in a particular degree.
generators(NCRightIdeal) -- Returns the generators of an NCRightIdeal
isHomogeneous(NCRightIdeal) -- see isHomogeneous(NCIdeal) -- Determines whether the input defines a homogeneous object
NCRightIdeal + NCRightIdeal -- Sum of NCRightIdeals
ring(NCRightIdeal) -- Returns the ring of an NCRightIdeal

For the programmer

The object NCRightIdeal is a type, with ancestor classes HashTable < Thing.
