Update README.md
Unpartitioned HiveTable
Add some standard time sources, and remove the miscellaneous trait

Preserve backwards compatibility for old job api.
Provide acceptable defaults for the new execution api.

This closes #238.
Fixes formatting in LoadExecution.
Adds counter to keep track of how many rows were filtered.

This is important to calculate the failure rate, since it is not
sufficient to calculate the failure rate based on the read count.
Adds some more comments for Filter and Validator.
Upgrades to sbt 0.13.7.
Upgrades to latest uniform version with scalding 0.12.
Derives the mode and Configuration from the Execution monad context.

This closes #239.
Using Joda time for partition and correcting alignment
Change execution tasks to take config objects and add Maestro main trait.

1. Provides configuration objects for maestro tasks,
   so the user can specify the config once at the start
   of the job and not repeat themselves below.
2. Provides a MaestroConfig object with factory functions
   which supply default values for most upload, load,
   sqoop import/export, and hiveTable configuration parameters.
3. Provides a runner trait which can be extended to form a main
   class.
4. Moves execution tasks and related classes to exec namespace.
5. Corresponding changes to documentation, tests, and examples.

This closes #252, closes #253, fixes #223, and closes #224.
Adds rich execution wrapper to run an execution with a modified config.
Adds a method to conf helper to add the timestamp to the output filename.

Adds default constructor for JobFailure and assertion to ensure error
code is < 0.
Fixes up load failure conditions.
Added Index Filter to Remove Columns based on Index
Changes default append mode back to true for viewHive in ViewExecution.

As part of the execution work it was accidentally set to false.
New methods for Sqoop import with SQL query
