    * starting Lua port of python implmention. Syncing commit
    
    * Bulk of Lua module port from Python done. Not tested, only static analysis. Need to work on binary strings. Started work on flatc lua code generation
    
    * Fixed all the basic errors to produced a binary output from the builder, don't know if it is generated correctly, but it contains data, so that must be good
    
    * fixed binary set command that was extending the array improperly
    
    * continued improvement
    
    * Moved lua submodules down a directory so their names don't clash with potential other modules. Added compat module to provide Lua versioning logic
    
    * Successful sample port from Python
    
    * working on testing Lua code with formal tests
    
    * continued to work on tests and fixes to code to make tests pass
    
    * Added reading buffer test
    
    * Changed binaryarray implmentation to use a temporary table for storing data, and then serialize it to a string when requested. This double the rate of building flatbuffers compared to the string approach.
    
    * Didn't need encode module as it just added another layer of indirection that isn't need
    
    * profiled reading buffers, optimizations to increase read performance of monster data to ~7 monster / millisecond
    
    * Writing profiler improvments. Get about
    ~2 monsters/millisecond building rate
    
    * removed Numpy generation from Lua (came from the Python port)
    
    * math.pow is deprecated in Lua 5.3, so changed to ^ notation. Also added .bat script for starting Lua tests
    
    * adding results of generate_code.bat
    
    * simple edits for code review in PR.
    
    * There was a buffer overflow in inserting the keywords into the unorder set for both the Lua and Python code gens. Changed insertion to use iterators.
    
    * fixed spacing issue
    
    * basic documenation/tutorial updates. Updated sample_binary.lua to reflect the tutorial better
    
    * removed windows-specific build step in Lua tests

-- automatically generated by the FlatBuffers compiler, do not modify

-- namespace: Example

local flatbuffers = require('flatbuffers')

local TestSimpleTableWithEnum = {} -- the module
local TestSimpleTableWithEnum_mt = {} -- the class metatable

function TestSimpleTableWithEnum.New()
    local o = {}
    setmetatable(o, {__index = TestSimpleTableWithEnum_mt})

    local o = TestSimpleTableWithEnum.New()
    o:Init(buf, n + offset)
    return o
end

    self.view = flatbuffers.view.New(buf, pos)
end
