Initial version.
Initial version of Anna's code.
Trying (and currently failing) to make repa arrays comonads.
Do the whole thing as a vector of vectors then we can use a plain comonad.
Add in the zero force from the particle on itself
Improve the arithmetic and add real data
Temporarily remove repa code until we get the vector code working
Tidy up vector code
Further tidy up of vector code
Yet more tidying. For example we can now run in steps on one hundredth of
a day and after 36500 we get back to approximately where we started
from.
Cosmetic change.
Move to using literate haskell for now and re-arrange similar concepts
to be grouped together.
Start writing the text for the blog to explain the implementation of
the Leapfrog Method.
More tidying to make ready for bloggin.
Use a form of literate haskell that pandoc seems to understand. In
theory it should understand Bird tracks (> ) but these seem to get
reproduced in the html :(
Start of using repa + some text for the (by now rather delayed) blog.
Some old leapfrog changes probably text for blogging.
More on calculating the point differences of all particles.
A big tidy up.
Find the forces for particles with identical masses.
