%description
Shiny application that performs bifurcation and phaseplane analysis of
systems of ordinary differential equations. The package allows for
computation of equilibrium curves as a function of a single free
parameter, detection of transcritical, saddle-node and hopf bifurcation
points along these curves, and computation of curves representing these
transcritical, saddle-node and hopf bifurcation points as a function of
two free parameters. The shiny-based GUI allows visualization of the
results in both 2D- and 3D-plots. The implemented methods for solution
localisation and curve continuation are based on the book "Elements of
applied bifurcation theory" (Kuznetsov, Y. A., 1995; ISBN: 0-387-94418-4).
