sql-surveyor

• Switch @ import to use relative path
• Fix logging error during initial SQL parse when logging option is disabled

Initial implementation of:

• Stored procedure execution parsing for PL/SQL
• Control flow statement parsing for PL/SQL

• Updated dependencies
  • Includes improved T-SQL, PL/SQL and PL/pgSQL parsing

• Adds ability to control how errors are handled while surveying a SQL script. Optionally choose between logging errors or throwing errors (or neither). By default SQL Surveyor will throw errors. These options are specified during SQL Surveyor instance creation (second constructor argument).
• Can now change the SQL dialect for a SQLSurveyor instance that has already been instantiated using the setDialect method.

Fixes #2.

• Fix handling of "tableName AS alias" syntax for PL/pgSQL
• Improve handling of "tableName AS alias" syntax for MySQL

• Detect referenced columns within subqueries in a SELECT list
• Fix aggregated output column detection in T-SQL
• Fix table location identification inside aggregation functions for MySQL, PL/SQL, and PL/pgSQL

• Add type attribute to the Token class. Tokens are now identified as a comment, identifier, keyword, literal or operator.

Fix column alias parsing for CASE statements

• Add support for column aliases in OutputColumns
• Improve consistency when parsing table names or aliases from output columns
• Attempt to finish parsing if an error occurs
• Fix bug where attempting to retrieve a subquery at a location between two other subqueries (would return the next subquery)
