* Space before colons in eos_utils.py help messages

* Enable extrapolation in eos_utils.py when NS is out of bounds

* Same check on shape in primary_mass and secondary mass

* Function to swap masses and spins of object 1 and object2

* Allow user to request for remnant_mass calculations: 1) extrapolation, 2) swapping object 1 and object 2 if mass2 > mass1, 3) treat as a (dark) BBH and NSBH with NS mass greater than a value probided by the user

* Renamned swap_companions to ensure_obj1_is_primary and generalized it

* codeclimate

* codeclimate

* Fixed line that was too long

* Fixed docstring and using keywords explicitly in all remnant_mass_* calls

* Renamed max_ns_mass as ns_bh_mass_boundary and improved help messages of functions

* Improved docstings

* Comprehensions in pycbc_brute_bank

* Complying to naming convention for spin components in spherical coordinates

* Update conversions.py

Fixing single code climate complaint.
