New estimated minimum transition time function and cleaned up general transition time function

Added a new estimated minimum transition time function based on the solution to a marginally-stable 2-dimensional Lotka-Volterra system. This function is used by shc_lv_transitiontime().

Removed support for coupling from shc_lv_transitiontime - not used and a bad implementation. Other cleanup.
