Calculates the number of lessons between 2 ranks or the rank after adding N lessons.
Syntax: LESSONCALC <skillRank> <percentage> TO <skillRank> <percentage>
This will echo back a line estimating how many lessons it will take to reach a particular rank.
Syntax: LESSONCALC <skillRank> <percentage> PLUS <number of lessons>
Echos a line estimating your rank and percentage if you were to learn N lessons.
NOTE: The skill numbers/ranks between IRE MUDs are only slightly different (i.e. "skilled" is called "master"), so you can either make the few modifications to match your MUDs numbers/ranks or use it as it is and avoid projecting over too far of a range.
