idk, git problems
changed method format
added a test in the postgres_adapter_test.rb file for testing the connection.valid_types check
test cases added to the sqlite3 and mysql adapter test files.
change the sqllite3_adapter_test.rb file to utilize the valid_type function properly. now all the sqllite3 tests are passing. working on postgresql now
postgres and sqlite3 tests created and pass.

trying to reolve branch issue
held the Kraken back
Use define method instead of class_eval

reverted back the changes for the Gemfile

changed the second method from class_eval to use define_method. Also, changes the type in the array to be a symbol using column_type.to_sym

created an inline call to column_type.to_sym

removed unnecessarily deprecated comments
Merge branch 'master' into col-prob
