Functions
Methods- join (args)
- 
    Join all tables given as parameters.
 This will iterate all tables and insert all their keys into a new table.
    - args A list of tables to join
 Returns:- 
        A new table containing all keys from the arguments.
    
 
- crush (t, set[, raw=false])
- 
    Override elements in the first table by the one in the second. 
Note that this method doesn't copy entries found in __index.- t table the table to be overriden
- set
            table
         the table used to override members of t
- raw boolean Use rawset (avoid the metatable) (default false)
 Returns:- 
           table
        t (for convenience)
    
 
- from_sparse (t)
- 
    Pack all elements with an integer key into a new table
 While both lua and luajit implement __len over sparse
 table, the standard define it as an implementation
 detail. 
This function remove any non numeric keys from the value set - t table A potentially sparse table
 Returns:- 
           table
        A packed table with all numeric keys
    
 
- hasitem (t, item)
- 
    Check if a table has an item and return its key.
    - t The table.
- item The item to look for in values of the table.
 Returns:- 
        The key were the item is found, or nil if not found.
    
 
- keys (t)
- 
    Get a sorted table with all integer keys from a table
    - t the table for which the keys to get
 Returns:- 
        A table with keys
    
 
- keys_filter (t, ...)
- 
    Filter a tables keys for certain content types
    - t The table to retrieve the keys for
- ... the types to look for
 Returns:- 
        A filtered table with keys
    
 
- reverse (t)
- 
    Reverse a table
    - t the table to reverse
 Returns:- 
        the reversed table
    
 
- clone (t, deep)
- 
    Clone a table
    - t the table to clone
- deep Create a deep clone? (default: true)
 Returns:- 
        a clone of t
    
 
- iterate (t, filter, start)
- 
    Returns an iterator to cycle through, starting from the first element or the
 given index, all elements of a table that match a given criteria.
    - t
the table to iterate
- filter a function that returns true to indicate a positive match
- start what index to start iterating from. Default is 1 (=> start of the table)
 
- t
- merge (t, set)
- 
    Merge items from the one table to another one
    
    Returns:- 
           table
        Return 
 tfor convenience
- map (f, tbl)
- 
    Map a function to a table.  The function is applied to each value
 on the table, returning a table of the results.
    - f function the function to be applied to each value on the table
- tbl table the container table whose values will be operated on
 Returns:- 
           table
        Return a table of the results
