input library for exporting anonymous metrics about users

 Libusermetrics enables apps to locally store interesting numerical data
 for later presentation. For example in the Ubuntu Greeter "flower"
 infographic.
 .
  - All data is stored locally in /var/usermetrics/.
  - No data is centrally collected via a web-serivice or otherwise, and
    no data is sent over the internet.
 .
 The only data that can be stored is numerical, for example "number of
 e-mails" or "number of pictures taken". No personally identifying
 information is stored using this library.
 .
 The Libusermetrics components are used by the Lomiri Operating
 Environment.
 .
 This package contain the libusermetricsinput shared library to be
 used by applications.
