                                          Class<?> listElementType,
                                          Class<?> eqnType)

Returns whether the given column type is compatible with an equation type

Parameters:

columnType - the column type

listElementType - the list element type, if columnType is List

eqnType - the equation type

Returns:

true if the types are compatible, false if incompatible
