Methods based on solve to solve a linear system of equations
involving WoodburyMatrix objects. These methods take
advantage of the Woodbury matrix identity and therefore can be much more
time and memory efficient than forming the matrix directly.
Calling this function while omitting the b argument returns the
inverse of a. This is NOT recommended, since it removes any benefit
from using an implicit representation of a.
# S4 method for GWoodburyMatrix,missing

solve(a, b)WoodburyMatrix object.
Matrix, vector, or similar (needs to be compatible with the
submatrices a@A and a@V or a@X that define the
WoodburyMatrix).
The solution to the linear system, or the inverse of the matrix. The
class of the return value will be a subclass of
Matrix, with the specific subclass determined
by a and b.
