Native functions(exported to lua):
-GenerateEngine:  returns engine id              (args: seed)
-DestroyEngine:   destroys corresponding engine  (args: rngID)
-NewSeed          re-seeds engine                (args: rngID, seed)

-MakeNewEngine    returns engine id              (args: seed)

        -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

Fixes numerous problems I won't go into

Josh Cooper 23b2d5eba5 Merge branch cxxrandom
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)

    Fixes plugin_init()

    Misread the lines indicated by lethosor to be excluded, had broken the plugin in the process.

    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
