Added support for the pollard survey type within the application. When a pollard survey is selected, a dropdown menu will appear while performing the survey and filling in the survey information. Along with this, a transect value has now been added to the sighting database as well. The default values for transects are either numbers or letters. The view option can be specified in the settings menu. #20

Continued work on adding support for the Pollard protocol. I added a field to the Survey table to keep track of how the transects are broke apart, distance or habitat. I also added a dropdown menu when a Pollard survey has been opened that show
all the current transects that have been configured on the device. This required the creation of another database table to store all the user created transect information. I also created a provider and manager for accessing that information. Each sighting is saved with an index into the lists that are generated in the dropdown menu for the transect. This will probably need to be changed to store the record ID of the transect from the database table. As the user will eventually be able to modify their transect list, I removed the Pollard mode from the settings files. The SurveyFragment and the EditSighting page were also modified to change their apearance slightly if a Pollard survey has been opened. A method still needs to be implemented for allowing the user to customize their list of transects. #20
