// Rundown on how I did this:
/**
 * calcEncounter() checks what faction territory you are in and pipes the respective faction into initilizeEncounter().
 * 
 * initEncounter() is pretty much the same however you can use forceFaction (set to true) to bypass the random raider/abomination chance.
 *  forceFaction will always be false unless under certian circumstances (eg. Lost Hills, Legion Territory, Malcom Holmes).
 *  Turns out the fight/flee variables work exactly how I want so I did not change them.
 * 
 * encounterMenuMaker() was changed to account for forceFaction. If forceFaction is set to true, EMM's equivilant forceOpt will take its value.
 *  If true it runs the code you had before, no changes. If it is false it will roll a dice to see if you get the normal faction, given by your switch statement,
 *  or a radier/abomination. If it is a radier/abomination it will then roll a 50/50. The code for both is the same as the default faction code except that
 *  'faction' will just be 'raider' or 'abomination' instead of the default.
 * 
 * I also implemented auto difficulty scaling. Instead of piping in 'encounterDiffOne' you just input the interger of it. This is because you cant
 *  use a string as a variable name and or whatever. Just trust me, this is the only way it works. initEncounter() will figure it out on the otherside.
