Provides simple interface for interacting with stellar model grids.

Installation
-----------

Install with ``pip install isochrones`` or by cloning the repository
and running ``python setup.py install``.

Depends on normal scientific libraries (e.g. ``numpy``, ``pandas``, etc.),
as can easily be installed trouble-free via, e.g., the anaconda python distribution.

For usage details, `read the documentation <http://isochrones.rtfd.org>`_ or
check out the `demo notebook <http://nbviewer.ipython.org/github/timothydmorton/isochrones/blob/master/notebooks/demo.ipynb>`_.

Stellar fits will want to use ``MultiNest``/``pymultinest`` if those packages are installed (recommended); otherwise the fits will default to MCMC fitting using ``emcee``.

Basic Usage
------------

For simplest out-of-the-box usage after installation, make a file called ``star.ini`` that
looks something like this::

Teff = 5770, 100
feh = 0.0, 0.15
logg = 4.5, 0.1
V = 10.0, 0.05

Any combination of spectroscopic or [supported] photometric properties, as well
as parallax, can go as properties into this file.

Once you've made this file, type ``starfit`` at the command line. Or if you want to be organized,
you can put ``star.ini`` in a folder called ``mystar`` [or whatever]
and run ``starfit mystar`` from the command line. The ``starfit`` script
will create an HDF5 file containing the saved ``StarModel``, which you
can load from python using ``StarModel.load_hdf``, as well as triangle
plots illustrating the fit.
