== Description ==
This function is used to create "custom events" for use in user-code, that act mostly like normal Roblox events. For example:
<code lua>
local lib = LoadLibrary('RbxUtility')
local sig = lib.CreateSignal()
--
sig:connect(function(message)
    print("Message: "..tostring(message))
end)
--
sig:fire("Hello, World!") --> Makes the event fire, so that all the handlers are called
</code>
Note that the LuaSignal class also supports all of the other properties of events, such as wait:
<code lua>
Spawn(function()
    local result = sig:wait()
    print("Result: "..tostring(result))
end)
sig:fire("Continue Message") --> Makes any waiting code continue, as well as firing connected functions
</code>

CreateSignal( )
Returns LuaSignal
Description: Returns a LuaSignal object which acts much like the real RBXScriptSignal objects, which ROBLOX events use, only implemented in-Lua for full control from within scripts.
