Removed excess cruft/fitting code
Self-contained data pre-processing script
Got basic plots back up and running

...with the data preprocessing moved to preprocess_data.py
Deleted unnecessary commented code
Implemented simple exponential fit function
Plots of fmax and k vs. lipo conc
Deleted irrelevant plotting functions
Refactored plotting of raw data into own script
Refactored lst squares exp fits into own script
Removed extra code from layout_140318
Initial implementation of MCMC fitting of exp to 140318
MPI exp_fit, sample plot func
Added alpha option to GlobalFit.plot_func
Force Solver to use inline to avoid MPI conflicts
Cmd-line args, sample/plot options
Makefile target, fits with fmax variable
Made lipo_concs_to_fit into a numpy array

Doing numerical operations on the list in other code was breaking. Makes
more sense for it to be an array rather than a list.
Fit k with Fmax varying and also fixed
Added bsub commands to rebuild 140429 fits
Plots of exp fits to curves

The new plots show the quality of the exponential fits to the data for
both fixed and variable Fmax. Also updated the Makefile to reflect the
new names of the image files.
