getNextStepVals.m

% Takes a list of indeces and a target column, and returns a vector of
% values cooresponding to the target at the input indeces + 1...
% Intended to check what values the immediate time-step has
% Contains a sanity check that inserts NaN into target_vector if an index+1
% step does not belong to the same series (hurricane).
