Description

Story

As a user, I want to define symbols so that I can define a regular expression of symbols to identify sequences of events that I care about.

Partition:
1) Limited to 1 match per partition in this story.

2) Note that the match in the data might not span the whole partition, that is, that matched rows could just be a subset of the rows in the partition.

Window:
1) Limited to 1 window per partition.

Other:
1) In this story, a single row can only match 1 symbol. A separate story will be added to support multiple matches, i.e., rows:symbols of 1:N.
