Update to version 2.8
Fix parserAssignment TeX output to use TeX rather than string for its value (typo from copying and pasting).
Fix Value::Matrix decompose_LR to return a Value::Matrix, not MatrixReal1. Fix solve_LR to call correct routine to get wwMatrixLR (it was renamed and still had the old name).
