utilities

Implements a simple key-value style database where character string keys
are associated with data values that are stored on the disk. A simple interface is provided for inserting,
retrieving, and deleting data from the database. Utilities are provided that allow 'filehash' databases to be
treated much like environments and lists are already used in R. These utilities are provided to encourage
interactive and exploratory analysis on large datasets. Three different file formats for representing the
database are currently available and new formats can easily be incorporated by third parties for use in the
'filehash' framework.
