The 'methods' function should return a list of methods for class definitions
that are built in to the interpreter:

>> methods ('meta.class')
error: [java] java.lang.ClassNotFoundException: meta.class
error: called from
    methods at line 49 column 16
>> m = ?inputParser;
>> methods (m)
Methods for class meta.class:

Both of these styles should return the list of methods for the 'meta.class'
class. I can get this list in a roundabout way:

>> m = ?meta.class;
>> cellfun (@(x) x.Name, m.Methods, 'uniformoutput', false)
ans =
  [1,1] = delete
  [2,1] = eq
  [3,1] = fevalStatic
  [4,1] = fromName
  [5,1] = ge
  [6,1] = getConstant
  [7,1] = gt
  [8,1] = le
  [9,1] = lt
  [10,1] = ne
