0.5.3 Alpha

Release includes the following fixes:

• Cleans up the inheritance of the models, there used to be duplicates of some of the data from the base class.
  removes calls to the ODM1.1.1 in the Session Factory Class
• Alters the db connection settings to prevent a connection from timing out when it has been open for a long period of time (like through wofpy)
• Adds better functionality for querying specimen datatypes through get related features, get results, and get result values.
• Cleans up the update/delete/create functions. SQL alchemy keeps these simple, every function is the same, basically you send in the object you want to change/delete/add and it takes care of it for you.
• fleshes out some of the get queries. they were missing needed parameters, or were throwing errors.
• Set up getResultValues to return a pandas dataframe, no matter what type of Result
• Fix a misnamed object relationship in Annotations object
