Implemented datamodule in SrTomo. Cookbook example of srtomo working but exposing too much of the inversion package. Should hide it in srtomo functions. Corrected mistakes in inversion.gradient and inversion.regularizer.
Smooth tomography function for SrTomo. Bugfix in gridder.interpolate: forgot to check if numpy.arange generates the right number of elements
Bugfix to mesher.dd.SquareMesh: get_xs and ys returning arrays with 1 less element than needed. Need also the coordinate of the last edge of the mesh (see pyplot.pcolor)
Traveltime extension module now receives velocity instead of slowness
Bugfix in mesher.dd.SquareMesh:   final data misfit: 0.755684
using prop={} in the constructor leads to bad things! {} creates an instance of a dict that is shared by all instances of SquareMesh. So messing with on (by using addprop for example) also messes with other instances. Replaced props={} with props=None
Better doc string for srtomo with doctest and example
Fixed exception handling in srtomo (catching wrong exception). Finished epicenter.flat_homogeneous with cookbook recipe.
Added compile option -fno-strict-aliasing to try to fix compilation error in Windows
Cleanup in TODO list (moved to Trello). Skeleton of inversion.gradient.levmarq. Remove step param from newton solver.
Removed leftover step variable in gradient.newton
Empty modules for heuristic and linear problems
Wrote better docstring for inversion explaining how to use the solvers and regularizers
Finished changing inverse solvers to factory functions. Adapted epicenter to new model.
Iterative recipe for epicenter. Fix bug in gradient solvers: updating the parameter vect using p+= changes the value of p, so all iterations spit out the same reference. in the end, a list of p per estimate would have all the same values
Fixed doctest for epicenter
Finished Levemberg-Marquardt solver. Put it in epicenter recipe for show.
Adapted srtomo to use new solver factories
Added minimum distance regularizer to epicenter + cookbook recipe.
Unfinished steepest descent (stopeed at line search part
Finished Steepest Descent with recipe for epicenter
