mml_with_parents: Auxiliary function to mml_cpt()
In kelvinyangli/mbmml: Learn Markov blankets using Minimum Message Length

This function calculates the mml score of a target node given its parents. There has to be at least one parent for the target. Natural log is used.

1 2	mml_with_parents(indexListPerNodePerValue, arities, sampleSize, parentsIndices, targetIndex, alpha, statingPara = FALSE)

`indexListPerNodePerValue`	indexListPerNodePerValue
`arities`	arities
`sampleSize`	sampleSize
`parentsIndices`	parentsIndices
`targetIndex`	targetIndex
`alpha`	A vector of concentration parameters for a Dirichlet distribution. Range is from zeor to positive infinity, length is equal to the arity of the target variable.
`statingPara`	If TRUE MML estimate of the parameters are also stated with extra 0.5log(pi*e/6) per parameter, otherwise 0.
