//***************************************************************
//* Table object 3.0
//* ------------
//*
//*   set t=Table.create() - instanceates a new table object
//*   call t.destroy()     - destroys it
//*   t[1234567]           - Get value for key 1234567
//*                          (zero if not assigned previously)
//*   set t[12341]=32      - Assigning it.
//*   call t.flush(12341)  - Flushes the stored value, so it
//*                          doesn't use any more memory
//*   t.exists(32)         - Was key 32 assigned? Notice
//*                          that flush() unassigns values.
//*   call t.reset()       - Flushes the whole contents of the
//*                          Table.
//*
//*   call t.destroy()     - Does reset() and also recycles the id.
//*
//*   If you use HandleTable instead of Table, it is the same
//* but it uses handles as keys, the same with StringTable.
//*
//*  You can use Table on structs' onInit  if the struct is
//* placed in a library that requires Table or outside a library.
//*
//*  You can also do 2D array syntax if you want to touch
//* mission keys directly, however, since this is shared space
//* you may want to prefix your mission keys accordingly:
//*
//*  set Table["thisstring"][ 7 ] = 2
//*  set Table["thisstring"][ 5 ] = Table["thisstring"][7]
//*
