store abspath -- needed for Postgres copy and good to have
first commit of CSV into SQL with Postgres and a test
- now using csv.dialect
- created new and more complicated test set
- updating tests with setup/teardown funcs and better globals
- updating tests to NOT use Table/Computer
adding more options for \COPY as kwargs and added try/except block to gracefully handle fail over to sql.extend()
 - created dialect mapping for multiple keyword arguments of different names/spellings but similar concepts
 - started sqlite integration and testing
first commit of mysql/csv loading
Merge branch 'master' into feature/csv_to_sql_natively
removing prints and adding info on mysql float truncation.
fixed typos, removed unused imports, created one dictionary for dialect_mappings, switched out `sqlalchemy.types.String` to `sqlalchemy.types.Text`, changed name of postgres test to `test_postgrest_into.py`, changed mysql testing to use npt.assert_amost_equal.  Still not happy about float truncation when using MySQL
Merge branch mrocklin-sql-string-types into feature/csv_to_sql_natively
Proper handling of when csv.header is None
adding postgres service to yaml script
uncommenting test and removing other uncessary comments
adding test for appending to existing table
adding encoding option -- still need to write test to validate
better handling of unsupported DBs and specific operating system calls.  Listed default encodings for MySQL
