Re: Porting "distance_sphere()" and "distance_spheroid()" to MySQL.

[Koji Okumura]

Thank you for your review.
At first, we selected PostGIS. (^p^;)
However, under the condition of our project, we found MySQL is faster than PostGIS.
Therefore we decided to use MySQL in place of PostGIS.
But, we had one problem.
MySQL has no function to return linear distance between two points of geospatial data.
I therefore created the functions that are compatible with PostGIS.

> Do you plan to add more PostGIS functions to this plugin?
I'm sorry that I don't have any plan yet.
However, I will add other functions when we need.

I would like to do. But I have no schedule yet.
