**
** Hash table object. Tables are key/value pairs with a simple hash function
** to provide rapid searching for keys.
**
** Tables can hold any data type. Special functions are available for
** tables of AjPStr values, but these are in the ajstr library,
** and start with ajStrTable...
**
** In general, these functions are the same
** but with different hash and comparison functions used. Alternative
** function names are provided in all cases to save remembering which
** calls need special cases.
**
** @new ajTableNew Creates a table.
** @delete ajTableFree Deallocates and clears a table.
** @modify ajTablePut Adds or updates a value for a given key.
** @modify ajTableMap Calls a function for each key/value in a table.
** @modify ajTableRemove Removes a key/value pair from a table, and returns
**                    the value.
** @cast ajTableToarray Creates an array to hold each key value pair
**                     in pairs of array elements. The last element is null.
** @cast ajTableGet Returns the value for a given key.
** @cast ajTableLength Returns the number of keys in a table.
** @output ajTableTrace Writes debug messages to trace the contents of a table.
**
** @attr Fcmp [ajint function] Key compare function
