List of changes

Version	Changes
2.0.0	modified storage for evolutionary tracks thus saving a lot of memory a dimensionless age parameter is introduced for the purposes of interpolation between tracks (using the same approach as in SPInS) new and more flexible implementation of frequency combinations added a batch mode (without status bar)
1.3.0	can run both in python2.x and python3.x included default distributions for priors and tight ball ranges can tolerate erroneous values of user_params when fitting observations added status bar for iterations (thanks to B. Rendle) added plots with evolution of walker percentiles
1.2.0	removed extrapolation beyond grid limits various subprograms rewritten in Fortran (thus accelerating the code)
1.1.0	added extrapolation beyond grid limits
1.0.0	initial version
