Rearranging things
Modifications

Changed the way that  sigma is calculated to reflect a lack of
instrument constraints, and I'm still tracking the bug that fails to
grab the last transit's SNR.
Read in function mostly there
Separating functions

I don't want to pass arguments through the parent function...
Added qual flag to read_in_fits
read_in_fits optional flag work
Newest optional flags
Added a few asserts
More interface stuff
read_in_fits working

function call returns time, flux, and error when called on a string, and
the optional arguments work.
Clean up.
SNR_calc

Established inputs and some optional arguments.
end of day

So, I realize that the varargin methodology is broken. ARG
Fixed read_in_fits optional arguments

Also added more documentation.
Fixed opt_args

but I haven't fixed the problem with the window yet...
end of day
Fixed SNR bug

Consistently finds transit minimums now.
Added quiet mode

And a testing script.
In progress
