Major Revision
update v2.0
=-=-=-=-=
Native functions(exported to lua):
-GenerateEngine: returns engine id (args: seed)
-DestroyEngine: destroys corresponding engine (args: rngID)
-NewSeed re-seeds engine (args: rngID, seed)
-rollInt generates random integer (args: rngID, min, max)
-rollDouble generates random double (args: rngID, min, max)
-rollNormal generates random normal[gaus.] (args: rngID, avg, stddev)
-rollBool generates random boolean (args: rngID, chance)
-MakeNumSequence returns sequence id (args: start, end)
-AddToSequence adds a number to the sequence (args: seqID, num)
-ShuffleSequence shuffles the number sequence (args: rngID, seqID)
-NextInSequence returns the next number in seq.(args: seqID)
Lua plugin functions:
-MakeNewEngine returns engine id (args: seed)
Lua plugin classes:
-crng
methods:
-init(id, df, dist) :: constructor
id - Reference ID of engine to use in RNGenerations
df (optional) - bool indicating whether to destroy the Engine when the crng object is garbage collected
dist (optional) - lua number distribution to use
-__gc() :: destructor
-changeSeed(seed) :: alters engine's seed value
-setNumDistrib(distrib) :: set's the number distribution crng object should use
distrib - number distribution object to use in RNGenerations
-next() :: returns the next number in the distribution
-shuffle() :: effectively shuffles the number distribution
-normal_distribution
methods:
-init(avg, stddev) :: constructor
-next(id) :: returns next number in the distribution
id - engine ID to pass to native function
-real_distribution
methods:
-init(min, max) :: constructor
-next(id) :: returns next number in the distribution
id - engine ID to pass to native function
-int_distribution
methods:
-init(min, max) :: constructor
-next(id) :: returns next number in the distribution
id - engine ID to pass to native function
-bool_distribution
methods:
-init(min, max) :: constructor
-next(id) :: returns next boolean in the distribution
id - engine ID to pass to native function
-num_sequence
methods:
-init(a, b) :: constructor
-add(num) :: adds num to the end of the number sequence
-shuffle() :: shuffles the sequence of numbers
-next() :: returns next number in the sequence
Adds missing function exports.
Fixes numerous problems I won't go into
Implements helper functions for random number generation.
Implemented using C++11 <random> library.
Exported Lua Functions:
- seedRNG(seed)
- rollInt(min, max)
- rollDouble(min, max)
- rollNormal(mean, std_deviation)
- rollBool(chance_for_true)
- resetIndexRolls(string, array_length) --String identifies the instance of SimpleNumDistribution to reset
- rollIndex(string, array_length) --String identifies the instance of SimpleNumDistribution to use
--(Shuffles a vector of indices, Next() increments through then reshuffles when end() is reached)

Cleans up cxxrandom.cpp
DFHack contributions specifies:
-spaces instead of tabs, so tabs were converted.
-C++ headers before dfhack stuff, so it was done
*Also added author name, creation date, and last updated date.

Updates cxxrandom, fixes instance leak
deleted header
moved definition to cpp file #lethosor
fixed singleton instance, no longer a pointer
commented out dfhack commands, now only init/shutdown and exported lua functions

Fixes RollIndex and Renames RollNormal
Renamed the Normal Distribution RNG function to fit the standard.
Now named RollNormal(m,s)
Fixed some wonky white space in the lua macro export block.
Fixed a stupid mistake with the RollIndex output. (it was outputting 0's)
Updated usage details.

Implements SimpleNumDistribution
Exported additional functions to lua.
Functions allow the generation of random 0-N index values.
Generation promises all unique values [0,N] will be returned once each when generation is run N times.

Implements cxxrandom
cxxrandom was implemented using a singleton.
This singleton provides an interface for generating uniform numbers, or numbers in a normal distribution, and also booleans(given the probability for the true outcome)
The singleton interface is wrapped in functions which are exposed for lua usage.
Integrated into plugins/CMakeLists.txt
