findANonZeroMinor(n,M,I)
Given an ideal, a matrix, an integer and a user defined Strategy, this function uses the randomPoints function to find a point in $V(I)$. Then it plugs the point in the matrix and tries to find a nonzero minor of size equal to the given integer. It outputs the point and also one of the submatrices of interest along with the column and row indices that were used sequentially.




The option MinorPointAttempts is how many points to attempt before giving up.
The object findANonZeroMinor is a method function with options.
