--------------------------------------------------------------------

Updated the requirements doc, seems more or less complete for this go around. 

Please let me know if you see something that needs addressing.

Here is the old interface:

{code}
create_indicator_variables (
    	source_table,
    	output_table,
    	categorical_cols,
    	keep_null,		-- Optional
    	distributed_by		-- Optional
)
{code}

Here is the proposed new interface:

{code}
encode_categorical_variables (
    	source_table,
    	output_table,
        categorical_cols,
        categorical_cols_to_exclude,	-- Optional
        row_id,					-- Optional
        top,						-- Optional
        value_to_drop, 			-- Optional
    	keep_null,			        -- Optional
        array_output,			        -- Optional
        output_col_dictionary,  		-- Optional
        distributed_by				-- Optional
)
{code}
