Merge()

def ost.table.Merge	(		table1,
			table2,
			by,
			only_matching = False
	)

Returns a new table containing the data from both tables. The rows are 
combined based on the common values in the column(s) by. The option 'by' can
be a list of column names. When this is the case, merging is based on
multiple columns.
For example, the two tables below

==== ====
x     y            
==== ====
 1    10
 2    15
 3    20
==== ====

==== ====
x     u
==== ====
  1  100
  3  200
  4  400
==== ====

when merged by column x, produce the following output:

===== ===== =====
x      y     u
===== ===== =====
1      10    100
2      15    None
3      20    200
4      None  400
===== ===== =====
