from d703b37 of interferometry:
==============================

In interferometry.py,

(*) Fixed a bug to check if key 'id' is present in attribute telescope before
computing primary beam in member function append_settings() of class
ROI_parameters

In primary_beams.py,

(*) Removed reference of ground plane in the call to dipole_field_pattern()
while using telescope id = 'mwa_dipole'. This is because ground plane pattern
effect has been detached from dipole field pattern
(*) Fixed bugs when telescope is set to mwa_dipole in primary_beam_generator()
