Imploding a table

LUA's concat method works just like PHP's implode, so simply needs to be called in a similar manner.

Returns a string containing each of the table entries, delimited by whatever delimiter is passed into concat

• PHP implode()
• Python .join()
• Javascript .join()

t = {'1','2','3','4'}
table.concat(t,"-") -- Gives 1-2-3-4
table.concat(t) -- Gives 1234
