validateMatrices

This helper function validates that the two input matrices, L and O, are of
the appropriate form to be interpreted by the other functions. In particular
they should be square matrices of 1's and 0's with all 0's along their
diagonals. We do not require O to be symmetric here.

Provides routines to check identifiability or non-identifiability
of linear structural equation models as described in Drton, Foygel, and
Sullivant (2011) <doi:10.1214/10-AOS859>, Foygel, Draisma, and Drton (2012)
<doi:10.1214/12-AOS1012>, and other works. The routines are based on the graphical
representation of structural equation models.
