Description

describeTable returns back a string which is too open and makes it hard for clients to introspect the column families of the table.

The data will be returned in the following format:

{ 'Standard1':

{ 'desc': 'Table1.Standard1(ROW_KEY, COLUMN_MAP(COLUMN_KEY, COLUMN_VALUE, COLUMN_TIMESTAMP))', 'flushperiod': '60', 'sort': 'Name', 'type': 'Standard'}

,
'Standard2':

{ 'desc': 'Table1.Standard2(ROW_KEY, COLUMN_MAP(COLUMN_KEY, COLUMN_VALUE, COLUMN_TIMESTAMP))', 'flushperiod': '0', 'sort': 'Name', 'type': 'Standard'}

,
'StandardByTime1':

{ 'desc': 'Table1.StandardByTime1(ROW_KEY, COLUMN_MAP(COLUMN_KEY, COLUMN_VALUE, COLUMN_TIMESTAMP))', 'flushperiod': '0', 'sort': 'Time', 'type': 'Standard'}

,
'Super1': { 'desc': 'Table1.Super1(ROW_KEY, SUPER_COLUMN_MAP(SUPER_COLUMN_KEY, COLUMN_MAP(COLUMN_KEY, COLUMN_VALUE, COLUMN_TIMESTAMP)))',
'flushperiod': '0',
'sort': 'Name',
'type': 'Super'}}

The CLI will also need to be updated to handle the new map that is returned
