to avoid operator resolution ambiguities when compiling single-precision

LLTMatrix, LUscalarMatrix, QRMatrix: Provided consistent construction, decomposition and solution interface

of symmetric positive-definite matrices and the solution of associated
linear systems.

Added 'typeOfInnerProduct' support to ensure the correct type is
returned from the matrix product operator.

This avoids serious problems with template parameter deduction when
manipulating blocks of different matrix types e.g. Square and
Rectangular.

Matrices: Rename private member 'nRows_' -> 'mRows_' for consistency with access member function 'm()'

Run foamNewFunctionObject -h for details

This avoids the need to check that the m and n dimensions are the same.

Also added the Field outer-product operator returning a RectangularMatrix

The blocks may be specified directly in terms of the size and location in the
parent matrix or with the size obtained from a template specified
VectorSpace or MatrixSpace type.
