Internal function: Check singularity of SVDed matrix

Checks whether matrix is singular based on singular values of SVD.

checkSingularitySVD(singularValues, tol, rtol, digits = 5)

`singularValues`	Vector of singular values.
`tol`	Absolute tolerance, singular if `min(singularValues) < tol`
`rtol`	Relative tolerance, singular if `min(singularValues) / max(singularValues) < rtol`
`digits`	The number significant digits to show in case a warning is triggered by singularity.
