Evenly Spaced Streamlines
The purpose of this package is to plot evenly spaced streamlines for a 2D vector field with more flexible style options than the standard function streamslice(). Specifically, this package includes:
+ "Fancy" arrow, taper, and texture styles as described Jobar & Lefer, 1997 
+ Explicit control over both minimum and maximum streamline spacing
+ Better selection of streamline step size for high line densities
