RemoveNaNAttributeSelector in Staged Selection on Regression Model

[Former user]

When using RemoveNaNAttributeSelector in attribute selection, attributes that have missing values for some elements, of which are a part of several compositions in the dataset, show up as being selected. See the code logs attached:

Turns out the issue is that if an elemental property is missing for a certain composition, all the attributes derived using that property will not be marked as missing (i.e., NaN). I've now changed the behavior of the attribute generator to make all of the properties are NaN if any element in the composition is missing attributes.
