A function to calculate reflection and transmission of an interfacial negative amplitude soliton incident on a step. Includes fission of a transmitted wave pulse into solitons.
Important constraint: hplus has to be larger than h1. hplus > h1.
Plots the incident soliton, the reflected wave pulse and reflected soliton.
Also plots the incident soliton, the transmitted wave pulse and transmitted solitons after fission.
Based on parts of the following article:

The input value A (amplitude of negative soliton) must be entered as a positive value. This way the function will not give an erroneous result. Please just enter positive values.
