LtargetE4:
A management procedure that incrementally adjusts the Effort to reach a target mean length in catches.
Description
A effort based version of the most biologically precautionary of four target length MPs proposed by Geromont and Butterworth 2014.

yrsmth
Years over which to smooth recent estimates of surplus production
xx
Parameter controlling the fraction of mean catch to start using in first year
xL
Parameter controlling the magnitude of the target mean length of catches relative to average length in catches.
Value
