CRAN submission 1.7.4

Merge pull request #231 from SimonGoring/master

Submitted 1.7.4 version for CRAN.

Neotoma version 1.6.2

Minor changes to functions to improve usability on the broader set of data types within the Neotoma Paleoecological Database:

• Bugfixes in get_chroncontrol, read.tilia based on experience in extensive testing. Improved the basic plot method based on tests against Tilia files in the Neotoma Holding Tank.
• Built more robust interpolation in read_bacon so that age models without interpolated dates can still be imported.
• browse now opens multiple datasets in the Neotoma Explorer at once.

New bug fix & features

Version 1.6.1 provides support for the analogue package's Stratiplot method, allowing the user to plot download and download_list objects.

Neotoma version 1.6.0

Bug fixes and some re-drafting of examples. New function get_closest searches for datasets close to an existing sample.

Neotoma version 1.5.1

Built for v3.3.0 of R, the package update includes a bug fix for records with multiple entries for the same taxa within a single stratum (an issue associated with dcast implementation) and a bug fix for get_dataset.

neotoma version 1.5.0

Version 1.5.0 of the neotoma package, available directly from CRAN. The new version includes faster download processing through the use of httr and jsonlite packages to process JSON returned through the Neotoma API, and the inclusion of a new function to read Tilia files, commonly used for paleoecological research.
