Various specialised versions of simple linear algebra operators.
TFC Revised version 3-Oct-97 TFC Added TC_MatXVec2 NPC Added NC_VecXMat IMS started conversion to VXL 18 April 2001
Some of the code in this file has been converted to use VXL, the rest has been #if-ed out. Only convert the other functions as they are needed, and after checking that a suitable function doesn't already exist in VXL.
