function.predicates - added isInteger
Closes #11 by handling preface arguments
Merge pull request #13 from raganwald/master

An implementation of unsplat that allows for prefacing arguments
iterators and about 1/2 of the test suite
Merge pull request #16 from raganwald/master

Ports functional iterators from allong.es (#15)
all tests in, plus some restructuring of the code
Merge pull request #18 from raganwald/master

Merges the remainder of the functional iterator tests
_.arity function fixes the arity
function.predicates - additional test for round floats, e.g. 1.0, are ints
function.predicates - added isNumeric and isFloat to round out numeric predicates
Merge pull request #19 from raganwald/master

Merge pull request #12 from pchristensen/function_predicates_isInteger

function.predicates - added isInteger
Added keepIndexed - similar to keep
Tests for keepIndexed
unsplatl unsplats the first argument of a function

Use case: unsplatl(function(args, callback) { ... })
alias for unsplat
keepIndexed is more of a builder than a selector
keepIndexed moved to builders, and params swapped
keepIndexed is more of a builder than a selector
Swapped args in test for keepIndex and also added another assertion to hopefully clarify its purpose
