This is a consequence on my indecision about using the semimajor axis or the semilatus rectum. To avoid singularities and problems (see #37) I should probably move to using the semilatus rectum definitively.

If I make this change, probably the special function introduced in #38 won't be needed anymore.

Added conversion between coe and mee
The conversion is made transitive and non singular through
the use of semilatus rectum instead of semimajor axis, see poliastro#62.
The case of polar inclination is still pending.

My indecision still holds, so I'm reopening this issue.

I find myself never dealing with parabolic orbits, yet I introduced this change and I find it extremely annoying for the remaining 100 % of my use cases. I'm thinking of reverting it once and for all.
