> Story
> As a data scientist, I want to be able to define multiple symbols per row for pattern matching.
> See
> http://madlib.incubator.apache.org/docs/latest/group__grp__path.html
> for a description of what a symbol is.
> Currently in 1.9, a given row can only match one symbol. If a row matches multiple symbols, the symbol that comes first in the symbol definition list will take precedence.   This story is about all matching symbols on a row being used.
> Acceptance
> The attached data set and query should should produce the following output, also on screenshot attached:
> Event Timestamp	User ID	Age Group	Income Group	Gender	Region	Household Size	Click Event	Purchase Event	Revenue	Margin
> 4/14/12 23:43	102201	3	3	Female	East	3	1	1	112	36
> 4/15/12 2:53	102201	3	3	Female	East	3	1	1	117	28
> 4/15/12 8:51	102201	3	3	Female	East	3	0	0	0	0
> 4/15/12 23:13	102201	3	3	Female	East	3	0	0	0	0
> 4/16/12 4:20	102201	3	3	Female	East	3	0	0	0	0
> 4/16/12 5:44	102201	3	3	Female	East	3	1	0	0	0
> There are symbol matches for:
> Gender=Female
> Region=East
> Household Size=3
