Version 0.1.0: Introducing `GenomicTable`

A GenomicTable is a DataTable with one of the concrete AbstractGenomicVector subtypes as a row index. It is similar, in spirit, to Bioconductor's GenomicRanges, but a GenomicTable isa DataTable, while Bioconductor's GenomicRanges is always a vector of ranges that may, or may not, also have an associated DataFrame of metadata. GenomicTable is experimental and is not yet fully-featured.

This version includes more range overlap features including discrimination between exact- and overlap-matches using an exact argument to findoverlaps, in, etc..

There are a number of internal changes including faster genopos, chrpos, chromosomes, etc. functions and a re-organization of the range search functions as methods on AbstractGenomicVector.

The names of range-related functions have changed. The each function for iterating over tuples of (genostart, genoend) pairs is now called eachrange mirroring the change in RLEVectors. Range searching functions are built on the findoverlaps kernel function. Rather than using separate vocabularies for exact- and overlap-matches, the usual search functions (indexin, findin, in, etc.) gain an exact argument.

This version is fully compatible with julia 0.6. (There are a few deprecation warnings about the new "where" syntax that will eventually be fixed by Compat.jl).
