Function generate

Generates data from a create table statement with options.
How data is generated depends on column types and options but the general idea is simple.
Generator adds 1 to previous data row by row so each column would have sequentially incremented number.
Given that we have the following statement,

 create table a (
   c1 char(5),
   c2 integer,
   c3 float,
   c4 binary(8)
 );

then we would get the following.

   c1      c2  c3    c4
L1 "a0001","1","0.1","b0000001"
L2 "a0002","2","0.2","b0000002"
L3 "a0003","3","0.3","b0000003"
L4 "a0004","4","0.4","b0000004"
