Increasing this function may tell various functions to multithread their operations. You may also want to increase allowableThreads.

- isRankAtLeast -- determines if the matrix has rank at least a number
- getSubmatrixOfRank -- tries to find a submatrix of the given rank
- recursiveMinors -- uses a recursive cofactor algorithm to compute the ideal of minors of a matrix

- getSubmatrixOfRank(...,Threads=>...) -- see getSubmatrixOfRank -- tries to find a submatrix of the given rank
