Allow for nodeClassification to predict on a one hot encoded target variable

[seankrobinson]

Is your feature request related to a problem? Please describe.
Currently, the oneHotEncoding function allows you to encode a variable into a list-like object. However, if used on a multi class target variable that is stored as a string (4 classes in my case), the nodeClassification function is unable to predict using the resulting list-like object. Forcing you to resort manually encoding the variable via CASE statements.

Describe the solution you would like
Allow for nodeClassification to use a one hot encoded list-like object as a target variable.
