this object is the bridge between the lanczos and spooles codes.
NOTE: POSIX multithreaded version
neqns -- number of equations
prbtype -- problem type
1 -- vibration, multiply with M or B
2 -- buckling, multiply with K or A
3 -- simple
mxbsz -- maximum block size
nthread -- number of threads
seed -- random number seed used in ordering
msglvl -- message level for SPOOLES programs
set msglvl = 0 for no output
set msglvl = 1 for scalar and timing output
set msglvl >= 2 for lots of output
msgFile -- message file for debug and diagnostic output
external objects, not free'd in the cleanup
A -- InpMtx object for the first matrix,
B -- InpMtx object for the second matrix
internal objects, free'd in cleanup
pencil -- Pencil object that contains A + sigma B
frontETree -- object that contains the front tree information
symbfacIVL -- object that contains the symbolic factorization
mtxmanager -- SubMtx manager object that handles storage
for the submatrices of the factors.
frontmtx -- object that contains the factorization
oldToNewIV -- object that contains the old-to-new permutation
newToOldIV -- object that contains the new-to-old permutation
ownersIV -- object that contains the map from fronts to threads
solvemap -- object that contains the map
from submatrices to threads
