Release of Version 0.4.0

AnaFlow provides several analytical and semi-analytical solutions for the groundwater-flow equation.

Notes

This Version brings some changes:

the input for transient tests changed from "rad, time" to "time, rad" as order of input (in line with output format)
the output for transient tests now preserves the shapes of time and rad (better for plotting in 3D)
the grf model is now the default way of calculating pumping tests in laplace space
the grf_laplace routine was optimized to estimate the radius of the cone of depression
the grf_laplace uses now the pentapy solver, so we get rid of the umf_pack dependency
grf_model and grf_disk are now part of the standard routines
